Expert dream analyzer Dr. Greg Cynaumon shared his insight into the meanings and symbols that surface from our subconscious while we sleep. The brain stays awake while the body sleeps, and while each person's brain is different, there are symbols such as water which tend to have a universal meaning (it signifies rebirth) he noted.

Most dreams only last 3-4 minutes "but seem much longer because they take place in the theater of the mind," Dr. Greg said. Left brain types such as mathematicians tend to dream somewhat logically, while creative people's dreams are often more bizarre, he explained.

Recurring dreams or nightmares indicate a person is not properly analyzing the meaning that is being continually presented to them, Dr. Greg said. One particularly frightening experience he said he had, when he was in private practice, was with a client who had returned from South America and was relating his troubling dreams. But the man was also interjecting personal information about Dr. Greg that would have been impossible for him know. It was "clearly something demonic going on with him," he commented.
