What's real?

What's real and what's not. Where does the dream end and reality begin. Is the dream your reality or your reality a dream. Is the touch, the taste, the feel in your sleep, as real as the words that you speak. Is what goes on in my world when I'm not awake real, or is it fake. If I dream of something that angers me, is it real because when I awake, the anger does not dissipate. When I touch her, kiss her, hold her near - is it fake because she is not here. If my dream feels real when I'm wide awake, who is to say that my reality isn't fake. Do I dream when I seem wide awake?
