I don't know if it is the high altitude or something even higher that makes you feel high like this? You know when you get to that point where everything just washes over you, like walking slowly through warm rain and watching the world swim past. Something else takes the wheel and you're not even conscious of the transcendence you are feeling because its working on such a deep seeded subconscious level that your brain is too blissfully ignorant to register, until you look down at the ground and realize you're hovering a few inches above it.
