A while back I had an extremely memorable experience with hypnosis, to the point that I spent the next two days drawing and writing about it.
Arwyn set the stage really well as the scene started, and quickly got me primed for herself and her friend TipTap to have their way with me. They then did an expert job of keeping me transfixed throughout the induction, their avatar and the show they put on with it gave me a lot to focus on - too much, even, but that was the point.
By the time the drop came around, I could hardly hold my head up - so when given the command, I went right down.
