As a kid, I had a really strange, reoccurring nightmare. It usually started with me sitting in my backyard, by the pool, or just hanging out with my family. The weather was always perfect, and I was always having a great time swimming, talking, whatever. Once I would start to think, “Life doesn’t get any better than this!” everything would take a turn for the worse. A huge, hairy woman would come barging through the fence, screaming and waving her arms around like a lunatic. She would take a lap or two around the backyard, scaring the whole family, and then steal me or one of my family members, never to return. From the day I started having this dream on, I was afraid of Wookiees (thats how hairy this woman was). Anyway, this was my childhood “monster.” A hairy Wookiee-woman.
Once every few weeks, I would wake up sweating, heart racing, and look around my room to realize there was nothing there to be afraid of. I always wondered what in my brain made me think of such a strange situation and monster. The human brain is (in my and many others opinion) one of sciences greatest mysteries. There are many things we do not know about the human brain; especially why we dream. Check out this video I found about dreaming. It gives a pretty good definition of what dreams are, medically, and also gives some pretty cool information about why we dream.
In the video, it explains how dreams are more often than not full of negative emotions; you’re more likely to have a bad dream than a good one. Some scientists believe this is because dreaming has a purpose— to prepare us to deal with stressful and frightening situations (like being attacked by a hairy woman). I find this to be pretty cool, actually, and I think studying and researching dreams, and why our own brains create monsters and nightmares we are so afraid of, is worthwhile.
