I've have dreams that seem more real or more vivid than others but never as real as reality. It's very easy to distinguish the difference. My dreams are illogical, not even the law of gravity is constant in my dreams. In my dreams I could be driving one second and on a roller coaster the next. In my dreams I've levitated and flown around. I've been shot in the head and amputated only to be fine in the next. I've skated around the streets on dinner plates. I've even dreamed in cartoon. Reality is always constant and logical, every day in reality I must live with the consequences of my past real choices. There's no question what's real.
