When you sleep, your physical body is resting and re-charging. Your brain encounter with millions of inputs in a day such as colors, passing bus/cars, animals, counting things, concentrating something, researching,events of the day, things you saw, felt, books read, programs watched, touched, doing many other things during your job, learning, and many more millions to count.

Older people saw dreams as portals for receiving wisdom from the gods. In modern era, it has been theorized that dreams were the “royal road to the unconscious”. Modern theories suggest it’s not as complicated as that. Dreams are a secret outlet for your repressed desires. Dreams are highly visual and often illogical in nature, which makes them ripe for the type of “out-of-the-box” thinking that some problem-solving requires, said Deirdre Barrett, a psychologist at Harvard University.
