The Four Stages Of Non-REM Sleep

There are four stages of Non-REM sleep. During Stage 1, the eyes are closed. One can be awakened without difficulty; however, if aroused from this stage of sleep, a person may feel as if he or she has not slept. The heart rate slows and the body temperature decreases during Stage 2. At this point, the body prepares to enter deep sleep. Stages 3 and 4 are deep sleep stages, with stage 4 being more intense than Stage 3. These stages are known as slow-wave, or delta, sleep. If aroused from sleep during these stages, a person may feel disoriented for a few minutes. REM sleep is the portion of sleep when there are rapid eye movements. Dreams occur during REM sleep. We typically have 3 to 5 periods of REM sleep per night. REM sleep is characterized by a number of other features including rapid, low-voltage brain waves detectable on the electroencephalographic (EEG) recording, irregular breathing and heart rate and involuntary muscle jerks. A night terror is a sleep disruption that seems similar to a nightmare, but with a far more dramatic presentation. A nightmare is merely a frightening or unpleasant dream. If you asked Sigmund Freud "why do we dream?" he would say our dreams are a secret outlet for these repressed desires.
Dream sharing is possible because all people share some kind of mental link (even though we're not consciously aware of it). The Noosphere is the idea that all human thought exists on its own plane so to speak. It's almost a collective unconscious of sorts. We all have access to it, but aren't consciously aware that we do or how we do. However, it is a very challenging goal; to share a dream. You really need to have friends that have a passion for lucid dreaming, and the skills to back up that passion. This is a totally next-to-impossible task for the casual enthusiast but well worth it when you finally connect and have this taste of objective mutual
