Maybe a hypnotic freeze fantasy. Using suggestive imagry to make me believe I am in a world frozen in time.
I think many people would describe freeze fantasy the other way round - you are frozen like a living mannequin or shop window dummy while the the world continues around you. There are two versions of this already on WarpMyMind, one that makes you go blank and forget what happened while you were frozen and one that allows you to experience it and remember.
These files are TrigFreeze1 and Trigfreeze2
See also Goddess Spiral's version GS-TrigFreeze2 and FreezeTest
which triggers you, leaves you frozen for 10 minutes then untriggers you
You need to be able to get into trance and have a degree of hypnotic suggestibility but I would say these are good files for hypnotic novices.
The interesting thing about these files is that other people can use and abuse you while you are frozen. It is essential to make sure that you want to be used and abused and agree limits before you let people freeze you. Only do it with people you know and trust.
The other version of freeze fetish, where the world is frozen in time, is a fantasy - so the best way to achieve it may be as a lucid dream. I would suggest you try
Cardigan - Lucid Dreams (which worked for me)
or CurseLucidDreams2 (but try the other file first as a curse is hard to remove)
