Dreams are probably the purest, sometimes very weirdest, type of fodder for stories. Some people foreshadow in dreams. Some people put flashbacks in dreams. Some people take the idea of a dream, the weird symbolism and the nonsense and the potential, and they turn it into a long-running graphic novel series. Hey, it works for them.
I went to a lecture about dreams in literature once while I was in college. Essentially, the lecturer’s points boiled down to: If it’s actually realistic and nonsensical, it won’t make sense, so either do it for style or plot or both, but for God’s sake don’t get heavy-handed with the symbolism.
Some people remember all of their dreams, apparently. I’m not certain whether that’s a gift or a curse. After all, nightmares fall under the dream category too. But dang, I’d say a good third of the dreams that I experience are lost when I actually wake up enough to go brush my teeth. (Now that’s a handy plot idea, isn’t it? Clairvoyant dreams remembered in scraps; clairvoyant, foreshadowing dreams that the protag forgets by breakfast the next day. Verisimilitude strikes again.) I’d like to be able to remember more of my dreams just so I could examine them.
Talking about the dreams you have is a no-no. It’s dead fun to talk about your own, and dead boring to have to listen to someone else’s. I remember in high school I had a “my dreams” blog for about two minutes before I got bored with it myself. But even if the only conversation you’re having is an internal monologue (which hey, aren’t dreams internal monologues anyway?), I still think it’s worth it to dissect dreams.
Not in a Freudian way, not in an “oh for the first act everything was red and for the third act everything was blue which symbolizes this” way. I mean in terms of the visceral way the dream feels.
Have you ever gotten to fly in a dream? Then use it! Oh my God, use it in your writing! Airplanes and hang gliders and bungee jumping aside, dreams about flying are the closest we’re going to get. Please take advantage of it. And the same goes for raw emotions. The sheer building horror or gut wrenching sadness that a nightmare gives you — the elation from one of those really good dreams, whether that was meeting a cute girl or eating a delicious cake — the half second when you’re waking up that you believe the dream was real — take it, save it, and write it. Look, writers are magpies. We take ideas from everything in our lives. Dreams are no exception.
