Sleep is divided into five stages, each with its own unique characteristics. Stage 1 is light sleep, Stage 2 is deeper sleep, and Stage 3 is slow-wave sleep. Stages 4 and 5 are REM sleep, where dreams occur.

REM sleep is characterized by rapid eye movements, increased brain activity, and vivid dreams. It's thought to be important for memory consolidation and learning.

During REM sleep, the brain's neurotransmitters are deactivated, and the brain's default mode network is activated. This leads to the surreal and often illogical nature of dreams.

There are many theories about why we dream, including the activation-synthesis hypothesis, the memory consolidation theory, and the problem-solving theory.

Nightmares are dreams that evoke strong negative emotions, such as fear or anxiety. They can be caused by stress, trauma, or certain medications.
