Serene?? hmm I'm not sure if I would call it that. I've had an astral projection experience once. I was definitely not serene or at peace. Another night terror actually. It's possible that it wasn't really astral projection...but I did see myself, and I could see everything around me...I was dreaming wwith my eyes open. Really really scary shit. I have another theory that I wasn't really alive at the time...that I had died for a minute and it was my spirit coming out of my body, but something brought me back. Wehn you have so many substances in you anything is possible I guess?
