Ok I thought this was very cool and I decided to share my expierience. So I am trying to astral project and have been trying for over a year now. I started listening to binaural beats and laid on my back. I eventually got to the point where my whole body was numb and I felt like I was floating. Then I waited a little while keeping my mind as blank as possible and then a rush of energy like a wave shot down my spine and made me way tingly. I felt like I was being stretched back and forth, up and down. I got excited though and accidentally opened my eyes. I closed them again and completely relaxed again and even quicker I felt this wave. I wonder is this what it means to have vibrations and am I getting any closer to astral projection. I also saw the ceiling with my eyes closed like my conscienceness was shifting and leaving my brain.
