From a quick read, a map is just a teaching tool to explain that you and the person you're working with likely have a different understanding of everything. They would also go further to suggest that a lot of the client's problems could be 'errors in the map.' This pretty much just ties into avoiding assumptions about your client's thoughts, as well as why you would use their language directly.

Here's some NLP lingo for things that happen to our 'map':

• Generalizations - bundling a class of experiences. EG - every trip to the DMV will suck.
• Deletion - incomplete recall of an experience. You had fun at the party, but forgot how much the drive sucked.
• Distortion - changing the quality of something. Recalling something incorrectly, but remembering that as true. Or, creatively linking two things, like the smooth texture of your keyboard keys to pleasure.

None of these behaviors are inherently 'bad,' just something to be aware of (or tinker with.)

Working with a map - NLP provides labels for language structures where something could be happening. I could run through the examples, but I think if you're digging into something with intent, you could just look for generalizations, deletions, and distortions, and dig in asking about that for more specifics. A lot of this boils down to "Really, are you sure?" or picking part any assumptions in there. I'll scribble down some of the more novel ones...

• Nominalization - a noun made abstract. Their example is "I want evil hypnosis." You can dig in and see what they'd like, just by digging in to that statement.
• Mind Reading - "I know you want (foo)." You can just call this out, or ask them why they thought it.
• Cause-Effect - these can be occasionally counterproductive. You can question whether these two are actually linked - like slower breathing and suggestibility.
• Complex Equivalence - or - reaching possibly erroneous conclusions. "I'm not a super-responder, so I won't be able to experience hypnotic amnesia" may be a good one to question.
• Presupposition - where truth is assumed and baked into the statement. "I really want to go into trance!" could let you dig into why they assume they aren't in trance, and how they'll know when they are in trance.

• If you ask a question, expect only surface level information. "I had fun" could translate to "I had a blast, and I'd love to do that again!" or "I had a blast, but I could do for a little less Micky Mouse voice in the middle of my session."

• You can listen to your partner and the details that they provide about an experience (or what they'd like) to learn more about them. It sounds obvious, but if they're into the kinesthetic sensations of being wrapped up by a snake, they'll talk about it when they ask, and you'll know what to feed back to them later.
• You can provide descriptions in a '4-tuple' of the VAKog senses - EG - VAK(og). This will help you rotate around the experience.
• Do you have problems giving suggestions in one modality? Use another modality. If they don't feel submissive, visually describe them as being submissive.
• If they have an abstract concept they want to experience, say - transformation or submission, you can tell them that they're seeing it, feeling it, or hearing it... Then collect information, and make that abstract concept concrete

• Words like "always" and "every" imply there are no exceptions
• Must, can, should will, mustn't, can't, shouldn't, won't all create "Modal Operators of Necessity or Probability"

• You can use a 'lack of referential index' to have a subject relate in an indirect way
  • "Some people find that they enjoy putting their shoes on."
  • "Good drones like to find themselves obeying orders."
• 'Comparative deletions' have the subject look for the deletion itself
  • Are you noticing how you're feeling colder, now?
  • That's better now, isn't it?
• 'Unspecified Verbs' make a process unclear.
  • "All you need is a slight shift to surrender, and your mind can make that change now."
  • Can you imagine how it'll be when you finally turn into a goo creature of my own image?
• 'Nominalizations' are nouns that can't be standardized or defined. EG...
  • "Feel my control / grip over you"
  • ".darkness over your mind, seeping in.

• 'Mind reading' uses phrases like "I know how badly you want to be my submissive subject," or things along the lines of "it's obvious, it's clear, apparently..., it appears that"
• 'Lost Performative' statements assign worth or value without explaining it.
  • "It feels good to be a cat."
  • "We know it's better for you to just let go, and we know it always feels better when you finally give up..."
• 'Cause-Effect' is a lot like Anthony Jacquin's 'linking' concept. Because A you B. If/then, because, makes, causes.
  • "Each breath as you look into my left nipple causes you to go deeper." (Just seeing if you're awake.)
  • "And as you press harder down onto the table, it just sinks in, sticking even more firmly."
• 'Complex Equivalence' includes means, because, and equals.
  • "And because you're such a good toy, you can feel your mind slowly beginning to melt."
  • "I can see the muscles around your eyes softening... you're starting to give in."
  • "You're just a needy little toaster because you want to be controlled so badly."
• Presuppositions require an assumption to be taken for the sentence to be parsed.
  • "Maybe you're not quite so eager, yet, because I haven't programmed you to be that way."
  • "As you continue to relax just a bit more, I'm not sure if your mind or body will begin to drift completely into bliss first."

• You know you can use Tag Questions to lengthen your yes set, right? (Isn't it, aren't you, yeah?)
• Double binds both have desirable outcomes.
  • "Did you want to but the car now or did you need to talk about it a little more first?"
  • Maybe just looking into my eyes helps you focus... or maybe instead it's causing those eyelids of yours to start dropping down, just like that.
• Embedded commands is just using 'analog marking' to cram a suggestion into a sentence. (I'm not sold on these, but eh.)
• Conversational postulates are just suggestions that look like requests.
  • Can you do me a favor and notice how relaxed your eyes are becoming?
  • Do you think you can allow yourself to go along with the flow as you start to listen to my words a bit more intently?
• Extended quotes wrap suggestions in a conversation with someone else - EG - like My Friend John when giving suggestions to 'John.'
• Selectional Restriction is anthropomorphizing or personifying something for your suggestion.
  • "I bet your hands are just burning to get down on the floor and beg for me."
  • "Are your eyes just watering and trembling for my affection and attention?"
• Factive (Awareness) Predicates use a presumption to use awareness to make a suggestion true.
  • And at this point, you've probably noticed your eyelids have already begun to become heavier.
  • Have you realized just how slow your breathing is becoming right now?

Keeping all this in your head is going to be a mess - sleepingirl suggests being aware of existence, timing, or quality presuppositions in conversation or reading will help you. Or....

• As you feel that transformation...
• Before you feel that transformation
• While you begin to experience that intense transformation
  You don't need to be sneaky about this! You can highlight this to your partner, especially in hypnokink settings.

Feel free to stack these. EG "When you realize that feeling of that transformation taking place inside... beginning to form.... you'll know that at this point - it's too far to go back." This creates a presupposition that at some point they'll realize a transformation is taking place, linking it to a feeling that they'll notice. This gives your suggestion two entry points.

All this aside, sleepingirl makes a point to keep in mind:

There should be no rules about how to conceptualize what makes up a suggestion; more so, you should take the techniques that are helpful and make sense to you.

Here's the 'hypnotically applicable' double bind...

• Often a question with an or.
  • Do you want (foo), or (bar).
  • Do you want (foo) when (a) or (b).
• Can be made ambiguous and less 'rejectable' with "I wonder if (foo), or (bar)."
• Can be tripled... "I wonder if (foo) will happen (a), (b), or maybe even (c.)"

An example of this would be "you are hot" vs "what you did was hot."

Robert Dilts breaks the hierarchy/levels:
A. Who I Am: Who are you? (Identity)
B. My Beliefs: Why did you do x? (Values)
C. My Capabilities: How did you do x? (Abilities and Methods)
D. What I Do: What do you/did you do? (Just actions)
E: My Environment: Where/When do you/did you feel x? (What happened)

• Conjunction Reframe - And, but, although, while, so
  • Your shoulders drop down, and you continue to find it easier to listen to the sound of my voice.
  • Your shoulders drop down, but you continue to find it easier to listen to the sound of my voice.
  • (Tinker with the 'feeling' of descriptions here.)
• One Word Reframe: Swapping or removing a single word
  • S: "I'm a little nervous..."
  • H1: "A little shy?"
  • Villain hypnotist: "Oh, feeling little afraid?"
• Comparison/Similarity Reframe
  • Shifting how things seem gradually...
  • "Doesn't the care I'm providing you seem a little dark? Your excitement... betraying you?"

You can use this to spice up your language. Instead of 'down' into trance (lower, deeper, falling) you can go for floating, suspended, flying, weightless. Or - if you say "your brain feels fuzzy," what else feels fuzzy? Like it's becoming stuffing, filled with cotton candy, like TV static, soft like polyfill. Or less kinesthetic - out of focus, hard to make out.

(As a footnote - don't be dumb and fall into the trap of believing your own metaphors. Minds aren't suggestion-accepting machines.)

• You are Here
  • Set their present baseline. Tell them their 'right now' so you can talk about 'another time' soon.
• You are there
  • Set the "what if" and "what would it be like if / when..." This is about creating an emotional state the subject can anchor to.
• You are back
  • This step is "optional," but you can make explicit suggestions on the way back. Bring changes back with you 'from the future.'

• Realistic Future Pacing
  • Walk them through (and possibly highlight parts of) a future event. "Hm... I bet you're thinking about what it'll feel like when (I put you back in that (situation) / feel thing for the first time), aren't you. "
• Making Triggers Stick
  • Have them go through what the trigger will feel like in the future, when it's allegedly stronger.
• Sadistic Pacing (Or just, unrealistic future pacing.)
  • Have them experience a playful threat in the future of something that 'might' happen. This is handy for situations that aren't really plausible, but can get them in the headspace.
• Presuppositions
  • Time based 'when' presuppositions have more effect than 'if.'
• Past Pacing - what if
  • Wouldn't it be amazing if you'd already (been in situation) for an hour?
  • What if I had already (created effect?)
• Contrasting
  • Contrast them to a previous position they used to have to highlight the changes. Maybe they didn't like triggers previously (like me,) and now they think they're fun and harmless. It'd be easy to tease me about just how far this would go.
• Memory Play
  • You can suggest past memories being harder to recall for effect, given that you take appropriate precautions.

How "present" are you in this experience, or VAK component? In this context, this is all it means. An 'associated' imagination would be imagining yourself riding a bicycle. A 'dissociated' view of this would be watching yourself ride that same bicycle from a distance, maybe from a bench, or in third person.

Basic:

• Identify the submodalities
• Change the submodalities
• Refocus on the current experience - helping your partner notice the contrast

Belief modification:

• Identify submodalities of the belief
• Get submodalities on something unclear
• Apply those submodalities to the original belief
• Introduce a new belief, with the same submodalities
• Diminish the old belief
• Give the new belief the submodalities of the old belief
• Future pace the new belief to test

Provide two options - one to escalate, and one to de-escalate. "We could try out this new induction, or we could just chat a bit." Or extending this with a "... or we can each go off and check out the rest of the event. Anything's good with me!"
