Associated Phenomena Of Lucid

Rapid eye movement (REM).

 When a person is dreaming, the eyes move rapidly up and down and vibrate. Scientific research has found that these eye movements may correspond to the direction the dreamer "looks" at in the dreamscape. This has enabled trained lucid dreamers to communicate with researchers while dreaming by using eye movement signals.

 False awakening.

 In a false awakening, one dreams of having awoken. The room the dreamer falsely awakens in is often similar to the room he/she fell asleep in. If the person was lucid, they often believe that they are no longer dreaming and begin their morning routine. The dreamer remains naive to the dream either until they realize they haven't actually woken up or until they really do wake up.

 Sleep paralysis.

 During REM sleep the body paralyzes itself as a protection mechanism to prevent the movements that occur in the dream from causing the physical body to move. However, this mechanism can be triggered before, during, or after normal sleep while the brain awakens. This can lead to a state where the awakened sleeper feels paralyzed. Hynopogic may occur in this state, especially auditory ones. Effects of sleep paralysis include heaviness or inability to move the muscles, rushing or pulsating noises, and brief hypnogogic or hynopogic imagery. Experiencing sleep paralysis is a necessary part of WILD (wake-initiated lucid dream), in which dreamers essentially detach their "dream" body from the paralyzed one.

Out of body experience.

An out-of-body experience (OBE or sometimes OOBE) is an experience that typically involves a sensation of floating outside of one's body and, in some cases, perceiving one's physical  from a place outside one's body autocopy. About one in ten people think they have had an out-of-body experience at some time in their lives.Scientists are learning about the phenomenon.Despite some similarities in their phenomenology and induction methods, EEG studies do not suggest an equivalence between OBEs and lucid dreams. Lucidity is strongly associated with stage 1 REM sleep but OBEs are far less consistent, producing EEG traces that can variously resemble stage 3 sleep, a waking, eyes-closed state or other uncategorized states
