I mostly dream in black and white. Once in awhile they are in color. I keep a pencil and paper next to my bed and write my dream on it when I awaken. Some, I only remember parts of. Yes, I look them up in a dream book. I believe our dreams have to do with us and that they are fragments of our subconscious helping us to put things together. I think there are dream books that are full of baloney and some that are written to help you figure your own way through the images you have dreamed. I have a book that deals with the latter.
