Dreams are remarkable. Scientists still can't explain what happens when people dream, why we have them or why people see them. There's also pretty convincing evidence that mammals and birds also dream. The shaman, medicine men and wise sages of various cultures around the world believe that dreaming is a trance-like state of being, during which a person feels both connected and at one with the universe. They believe, that in this particular state it is possible to discover secrets from beyond: How the universe works or see fragments of the past or future. Normally after waking, the average person can't remember what they dreamed about or merely have a vague recollection of a surreal scene or a few cloudy snippets of what happened.
