They aid us in reviewing past events, reminding us of parallels in the resent. They protect sleep by disguising stimuli such as anxieties that would otherwise awaken us. Dreams have a deeper functions as well. They may provide pathways to recovering repressed or forgotten memories, whether from childhood, infancy, into-utro experiences, or even from past life. Past life memory fragments often emerge in the dream state, particularly in those dreams in which the dreamer sees scenes from the years of centuries preceding his or her birth.
Dreams can be psychic or precognitive. Often these particular dreams can predict the future. Accuracy varies because the future appears to be a system of probabilities, and because the ability of people accurately interpret their dreams itself varies tremendously. These psychic or precognitive dreams are experienced by many of all cultures and background. However, many people are shocked when their dreams literally come true.
Another type of psychic dream occurs when communication with a person at a distance is experienced. The person may be alive and geographically distant, or the communication may be with the soul or consciousness of someone who has died, such as a relative or dear friend. Similarly, there may be communication with an angelic spirit, a teacher, or guide. The messages in these dreams are usually genuinely moving and very important.
Travlling dreams also occur. During these dreams, people have experienced of visiting places to which they have never physically been. Details of what they see can later be confirmed. When one actually visits the geographical place, months or years after the dream, a feeling of deja vu or familiarity may occur. Sometimes the dream traveler visits places that do not seem to exist on this planet. These dreams may be far more than nocturnal imaginings. They may be mystical or spiritual experiences, accessed because the usual ego and cognitive barriers are relaxed during sleep dreaming. Knowledge and wisdom acquired during this type of traveling dream can transform lives.
