I also tried it last night.
It sure is a kickass technique to relax.
I did successfully the Relaxation , Reverse Blinking , Sleep paralysis , but after i entered the HI i lost it.
It was my first time to reach HI though and i did it with no problem at all.
I just did what you said.

My problem with the HI is that after the vibrations i thought i was seeing things but i was losing them at the same time.
I said to myself this should be HI and i tried to do the 2 tips you said with no success at all.
could someone please Describe for me the HI?
