Looking for a word to describe this feeling.

I am looking for a word that accurately describes this feeling. I took mushrooms and towards the end I felt a extreme feeling of relief, happiness, clearness, as if everything in the world was ok, an almost higher plane of existence feeling. I get this feeling still when listening to certain music that I listened to during the trip. When I feel this I can almost imagine myself in a world where everything is just great, there are no problems, an almost surreal feeling. I don't really know how to explain this other than it is very different from any other feeling I ever felt.
