These sand castles…
I really like introspection like induction, when hypnotist explains what she will do to me, tells me how her words starts to affect my thoughts, things like that.
If this is combined with soft whispers, I becomes instantly hooked to her voice and her words for the rest of session.
Good one is also conversation like induction (for example with rhetorical questions, eg. 20 Questions, partial in Cause & Effect), that way I can stop thinking about hypnosis and everything else and just align my thoughts with hypnotist words.
Story based induction is great too, but mostly when is related to session (like in The Contest or Cause & Effect), if is not related the sudden change in topic when induction ends can cause awareness of trance.
Ah, and I love these sneaky ones, like: What is square root of… SNAP!, or: I will count to 5 and then snap my fingers, 1…, 2…, 3…, SNAP!
