I do, although I don't always think of it that way. I describe it like the world should be in 3 dimensions, but I live in a world that's 2 dimensional. Flat. Feeling like the world is tilted; the floor is at an angle. Feeling like I'm 'light' - not floating, just light. Ringing in my ears (I hate that one.) Feeling like my head is getting larger like a balloon. You know, the usual.
