I think trying to get this feeling is the reason why people drink alcohol, except I don't get like this when I'm drunk. It takes me a couple of sips of something alcoholic to become light-headed and giddy - pleasantly drunk, then a couple more sips and I feel terrible - alcohol is a depressant, after all. I think I prefer getting drunk on surreality. But it's very odd :)
