You see them depicted all the time on television, movies, litereature, dreams that seem so real that even once you wake up, you feel as though it was a waking experience. But how common are they? I have them occasionally. Sometimes they are so real that it takes a lot of telling myself over and over that it didn't happen, that I didn't really go out in public and make a fool of myself or whatever else the dream may have been about. The biggest problem is that often, whether it is the next day or a week later, I have a great deal of difficulty distinguishing between memories of actual events and those of the dream. I was wondering what others' experiences are like in this respect.
