Here is the preflight checklist I am currently trying to use before each hypnosis session. I have it on my phone, so I can actually check it. As of my most recent Christmas travel, where I forgot one of the few things I absolutely couldn't do without, I'm convinced of the need for written checklists rather than trying to keep it in your head.
* How do you feel now?
* What is your timeframe?
* Bathroom trips
* Cellphones turned off
* Two glasses of water
It was important to me to keep it very short and very relevant. Here's a checklist for the first time working with a new person:
* Language to avoid [real example: someone who did not like the word "relax"]
* Physical problems
More questions for an experienced hypnotee:
* Do you feel confident you can bring yourself out of trance if something is bothering you?
* What you don't like and like in hypnosis.
* What kind of aftercare do you need?
Finally, a checklist for the end of the session that I plan to start using:
* Suggestion of remembering everything from the trance.
* Cancel all suggestions.
* Give an opportunity for feedback, particularly about things that rubbed them the wrong way.
* Allowing time and supervision to come back to reality.
Again, keeping it simple and short with an eye to using it, though I may find more things to add over time. You will notice that there's almost nothing relating to negotiation, which is always a part of a hypnosis scene, even when quick and mostly implicit between longtime partners. That's because I think checklists are not very helpful for negotiation, which I will be writing about in a future entry.
Edited to add: I should have said that this is a bare bones checklist for the situations I most often find myself in. Which is trancing with people who I know at least a bit socially already - so for example, I already know their pronoun preferences, and have a good idea about what kinds of casual touch are ok. (I'm thinking of whether there's going to be a sexual aspect to the trance to be part of negotiation, a separate thing) You can check out this much more complete checklist for ideas for one that might apply to broader situations.
