REM sleep
"REM" stands for "rapid eye movement" – and rapid eye movements are also characteristic of REM sleep. During the course of a night, we go through several such REM phases, which are interrupted by non-REM phases. REM sleep is characterized by rapid eye movements, low-amplitude brain activity of mixed frequencies, and reduced muscle tone. Pulse and respiratory rate, on the other hand, are increased. In addition, we dream particularly vividly and intensely during these phases. People who are awakened from REM sleep often report vivid, concrete, and emotional dreams, while those awakened from non-REM sleep tend to report more abstract dreams that resemble thoughts.
