I've heard of people having as many as 10 dreams in one night. I'd like to know what counts as a dream. In my dream journal, each written entry is usually one long description. Upon waking up, I try to write down as many details I can remember. The thing is, I'm not sure where to separate the dreams, because I classify it as one long dream with a bunch of different stuff happening. It's like a movie with different scenes, but its still one movie. So I guess my question is, what is the basis for distinguishing one dream from another dream? In other words, if you have multiple dreams in one night, what separates one dream from the other?
