I have worked with the Astral Trance one, trying to induce an OBE. Although I did not succeed, its not because of the tape but more because I was in turmoil in my life and had too much stuff in my head.
I can say though that everytime it would get me very close to doing it.
My arms would easily go but the head and body would stay put.
I actually would have goosebumps at a predetermined place because the music/noise would instantly activate my body to almost do it.
I am convinced that if I had done this in another period in my life, it would of worked....maybe I should work on that again now!
Also, I don't want to highjack the thread but Tom Kenyon also does this for me. He is the real deal and channels the arcangels and lets them sing.
I only have the free version that you can find on the net, but for sure it is very good to relax and feel healed.
