Wow! I have spent many, many hours trying to describe that feeling that I know so well. It's pretty difficult. The only word I can usually think of is numb. You did such a good job. This is the only poem I've come across that describes this feeling. Hopefully you aren't in a situation where dissociation is necessary...at least not constantly. I agree with jezabel 100%...it's haunting, and it's definitely beautiful.
