I very well know the difference between the real world and in the dreamworld. Everything feels kind of fuzzy and transparent in my dreams, if that makes any sense. Everything has that blurred and odd feel to it. For one, the geography in my dream universe is different but it's always the same in my dream world, doesn't change.

I guess my biggest problem at times is when I wake up sometimes I feel as if I'm the dream the dreamworld of me sleeping of the real world, like if his sleep was disturbed I would just disappear. Not as much a difference of discerning worlds but it's me's.
