PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Frequent, vivid dreams may be related to stress, medications, sleep disorders, or early pregnancy. While we think of sleep as a time for recharging the body, the brain is actually quite active during sleep-dreaming. Our dreams can be soothing or scary, mysterious or helpful, and realistic or fantastical.

Detailed explanation-2: -Vivid dreamlike experiences-called hypnagogic or hypnopompic hallucinations-can seem real and are often frightening. They may be mistaken for nightmares, and they can occur while falling asleep (hypnagogic) or waking up (hypnopompic).

Detailed explanation-3: -While dreams are known to be highly visual, psychotic hallucinations are primarily auditory.

Detailed explanation-4: -Hypnagogic hallucinations are vivid visual, auditory, tactile, or even kinetic perceptions that, like sleep paralysis, occur during the transitions between wakefulness and REM sleep. Examples include a sensation of impending threat, feelings of suffocation, and sensations of floating, spinning, or falling.
