Dreams are hallucinations that occur during certain stages of sleep. They’re strongest during REM sleep, or the rapid eye movement stage, when you may be less likely to recall your dream. Much is known about the role of sleep in regulating our metabolism, blood pressure, brain function, and other aspects of health. But it’s been harder for researchers to explain the role of dreams
At night everything slows down. We aren't required to focus on anything during sleep, so our brains make very loose connections. It's during sleep that the emotions of the day battle it out in our dream cycle. If something is weighing heavily on your mind during the day, chances are you might dream about it either specifically, or through obvious imagery. For instance, if you're worried about losing your job to company downsizing, you may dream you're a shrunken person living in a world of giants, or you're wandering aimlessly through a great desert abyss.

We know that the rear portion of our brain gets pretty active during REM sleep, when most dreaming occurs. Some think that it's just the brain winding down for the night and that dreams are random and meaningless firings of the brain that we don't have when we're awake. The truth is, as long as the brain remains such a mystery, we probably won't be able to pinpoint with absolute certainty exactly why we dream.
