Wow. Just read the entire thing. I have had very similar experiences on acid and shrooms. I believe that people who have not experienced LSD (or something similar) don't really see the world the same as a person who has.
The person who wrote down that experience is obviously a good writer and was able to describe the feelings pretty accurately, but there are certain things that u will experience while on lsd that are just unexplainable. I really can't come up with the words to describe the things I have experienced and felt while high on lsd.
I think everyone should try lsd at least once.
