About a week ago I had an experience that gave me a few questions. I first started with breathing exercises to relax. My body went numb and i then did 61 point relaxation which worked well and took me to a new level of relaxation and SP. I then was sort of hopefully anticipating HI and after none came I did a little daydreaming. I sort of saw faint light patterns projected, but I wasn't sure if I was seeing them or just imagining them. Then suddenly I saw more light and focused my eyes towards it. Shortly after this my eyes slowly opened up involuntarily. I did an RC and i was awake

This gave me questions: When do you consider SP to really take place. The first level of numbness or the really deep heavy kind?

Will you definitely know when you're seeing HI? What can you expect? and how can you transition into the next phase after SP.
