The Purpose of Dreaming

dreamSince early history man has been fascinated with the occurrence of dreams. Before the means for dream research existed, people theorized as to the meaning of dreams and why we have them.

Monophasic Sleep Pattern

mammalsHave you ever heard of monophasic and polyphasic sleepers? While 85 percent of all mammals are polyphasic sleepers, humans fall in the minority of monophasic sleepers. But it wasn’t always that way. There are several theories as to when humans went from being polyphasic sleepers to monophasic sleepers. One theory holds that it was back some time between 70,000 and 40,000 BC that Neanderthal man shifted from a polyphasic to a monophasic sleep pattern.
