During the sleepwalking stage of sleep, a person may get up and move around while still being asleep. This can include activities like walking, talking, or even eating without being fully aware of their actions. It occurs during the non-REM stage of sleep and is considered a type of parasomnia.
Sleep paralysis typically occurs during the stage of sleep known as REM (rapid eye movement) sleep.
The pituitary gland releases growth hormone during the deep stages of non-REM sleep, particularly during slow-wave sleep. This hormone plays a key role in growth, metabolism, and tissue repair.
Slow wave sleep occurs after Stage 1 and Stage 2 sleep, and prior to REM sleep. There is more slow wave sleep present toward the beginning of the night, while more REM sleep is present toward the end of the night's sleep. In slow wave sleep, delta waves are present on the EEG (Electroencephalogram), which measures brain activity. These waves are long and slow, as opposed to the sharp waves of Stage 2 sleep. It is ecause of the shape of these waves that the stage is called slow wave sleep.
Dreams mainly occur during the rapid eye movement (REM) stage of sleep, which typically happens around 90 minutes after falling asleep and recurs in intervals throughout the night. Non-REM sleep stages also involve some dreaming but they are usually less vivid and memorable compared to REM stage dreams.
Rapid eye movement is common during sleep but when it happens when a person is awake, it is considered to be abnormal and is called nystagmus. It is often caused by the abnormal function in part of the brain or the inner ear.
Stage 4
Sleepwalking disorder (somnambulism) occurs when the patient is capable of complex movements during sleep, including walking. Sleepwalking occurs during stage 3 and stage 4 NREM sleep during the first part of the night.
It happens in the 4th stage
Sleepwalking usually only occurs during stage 3 of non-rem sleep.
Stage 4.

Sleepwalking usually occurs during stages 3 and 4 of the NREM part of your sleep cycles. NREM means the non-rapid eye movement stage. REM means rapid eye movement. Night terrors aren't exactly well understood, but most professionals will agree that they happen during the NREM stages of your sleep cycles.
Contrary to popular belief, sleepwalking occurs in the deepest stages of sleep, called delta-wave sleep or stage 4 sleep. REM sleep, by contrast, is rapid eye movement sleep, during which the body is in a near-paralysis state.
Sleep paralysis typically occurs during the stage of sleep known as REM (rapid eye movement) sleep.
REM sleep, also called rapid-eye movement sleep, is when dreams occur. Our brain is more active during REM, it generates 'smaller and faster brain waves' (Hockenbury 142). The first stage or episode of REM is brief, lasting between 5-15 minutes. NREM sleep (non-rapid-eye-movement, is when brain activity slows down. NREM sleep is grouped in four stages. Stage 1 lasts only a few minutes during which you teeter on the edge of sleep and consciousness. During this stage it is very easy to be woken up by the littlest sounds. During stage 2 breathing becomes rhythmical. Stage 3 and stage 4 of NREM "are often referred to as slow-wave sleep" (Hockenbury 142). Sleepwalking is known to occur during this stage.

They occur during REM sleep, usually in the second half of the night
No. During the human sleep cycle in stage 3 and 4 sleep we enter what is known as Cataplexy ( Temporary paralysis of the bodies muscles) so we cannot move, or act out our dreams. There are rare exceptions to this of course... The sleep disorder Somnambulism ( AKA Sleep walking), in which people experience episodes of sleepwalking or performing actions in their sleep. Boys are more apt to have Somnambulism. 25% of all Children sleepwalk.
