| is light sleep where you drift in and out of sleep and can be awakened easily. In this stage, the eyes move slowly and muscle activity slows. During this stage, many people experience sudden muscle contractions preceded by a sensation of falling. |

Definition
| eye movement stops and brain waves become slower with only an occasional burst of rapid brain waves. When a person enters. Irregular EEG with sleep spindles |
|
|
Term
|
Definition
| extremely slow brain waves called delta waves are interspersed with smaller, faster waves. theta and delta waves begin to appear, nightmares and night terros |
|
|
Term
|
Definition
| the brain produces delta waves almost exclusively. Stages 3 and 4 are referred to as deep sleep, and it is very difficult to wake someone from them. In deep sleep, there is no eye movement or muscle activity. This is when some children experience bedwetting, sleepwalking or night terrors. vital signs low |

Term
|
Definition
| breathing becomes more rapid, irregular and shallow, eyes jerk rapidly and limb muscles are temporarily paralyzed. Brain waves during this stage increase to levels experienced when a person is awake. Also, heart rate increases, blood pressure rises, males develop erections and the body loses some of the ability to regulate its temperature. This is the time when most dreams occur, and, if awoken during REM sleep, a person can remember the dreams. Most people experience three to five intervals of REM sleep each night. increased vitals. dreaming, movement of eye lids. neurol debugging, necessary for emotional health |
