Do you dream each night? Do you keep a dream journal? Can you control your dreams (a technique called "lucid dreaming")? Have you ever written anything inspired by a dream before?
In my non-fiction class, another student wrote his piece on how he tried to learn lucid dreaming. In order to do so, he started a dream journal and wrote down his dreams in order to look for patterns in them.
As a psych student, I hear a lot about dreams and dreaming and all the different theories of what they are and how (or even if) you can interpret them. The truth is, all they really know is that, even though everyone dreams, it is a unique, individualized process and no one knows for certain what they mean... but if anyone could figure one out, it would be the person who dreamt it.
