Has it ever happened to you, that you were so nervous about doing something that when you did it you were like out of your body? It has happened to me some times, when I had to present a project in school, so much tension before but when you start talking it feels strangely relaxing and like you're out of your body
I made a thread about astral projection just recently. I haven't had this happen to me, but the other day I tried. I was feeling very relaxed in the morning and heard a loud buzz in my ears before snapping awake. That's the first step!
