During REM (rapid eye movement) sleep, the body experiences temporary muscle atonia, meaning that most voluntary muscles are effectively paralyzed to prevent acting out dreams. Therefore, physical movements like walking or talking do not typically occur during this stage. Additionally, during REM sleep, the body does not engage in the deep restorative processes associated with non-REM sleep, such as tissue growth and repair.
Truly "deep" sleep does not occur during REM sleep. REM sleep is when you are dreaming. It is deeper than light sleep, but not as far down in unconsciousness as "deep" sleep.
No, REM (Rapid Eye Movement) sleep does not occur during stage 3 sleep. Stage 3 is characterized as deep sleep, which is part of non-REM sleep. REM sleep typically follows the non-REM stages, occurring after stage 3 in the sleep cycle. During REM sleep, brain activity increases, and vivid dreaming often occurs.
They occur during REM sleep, usually in the second half of the night
Approximately 80% of dreams occur during REM (Rapid Eye Movement) sleep. REM sleep is characterized by increased brain activity and is often associated with vivid and more memorable dreams. While dreaming can occur in other sleep stages, the most intense and elaborate dreams typically happen during REM.
REM (Random Eye Movement).

Very recent research suggests that dreams that occur during REM sleep tend to be more agitated and troubled than dreams that occur during non-REM sleep. More research is being done to better understand the difference.
Sleep paralysis typically occurs during the stage of sleep known as REM (rapid eye movement) sleep.
No, during REM sleep, the brain is active, however any muscle activity is suppressed to prevent you from acting out dreams. During stages 3 and 4 of NREM sleep sleepwalking is known to occur.
Yes, it is possible to experience dreams during non-REM (NREM) sleep, although they are typically less vivid and less memorable than those that occur during REM sleep. NREM sleep consists of different stages, and dreaming may happen primarily during the lighter stages of sleep. However, most vivid and narrative-driven dreams are associated with REM sleep.
Sleep is prompted by natural cycles of activity in the brain and consists of two basic states: rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep, which consists of Stages 1 through 4. During sleep, the body cycles between non-REM and REM sleep. Typically, people begin the sleep cycle with a period of non-REM sleep followed by a very short period of REM sleep. Dreams generally occur in the REM stage of sleep. Then the cycle repeats all over again.
The dreams that we remember tend to only occur during REM sleep. However, new research is showing us that dreams can actually happen in NREM sleep. Research is still being done to determine exactly what kind of dreams when have in the different stages of sleep.
