I find people who need imagery to write fascinating. I know I am the strange one in this but, I don't dream in images. I dream in words. Occasionally there will be an actual scene that I visualize but I dread those. Like I dreamed about my mother calling to tell me my father didn't make it out of surgery and it played out just like the visual dream showed me the very next day. But, my normal, no need to freak out dreams, are all in words, sometimes spoken but most of the time its like reading a book rather than watching TV.
