Dreams have always been a mysterious function of the mind. They mainly occur in the rapid-eye movement (REM) stage of the sleep cycle when brain activity is still high, resembling that of being awake. It is thought that the average human dreams between three to five times a night, but with the other dreams occurring during other stages of sleep, these dreams are much less vivid or memorable.
Analyzing dreams has been a psychic discipline for centuries and mankind are convinced that dreams can predict the future.
