Why do people dream??

Dreams are stories and images that our minds create while we sleep. They can be entertaining, fun, romantic, disturbing, frightening, and sometimes bizarre and unrealistic.

Some reason for why we sleep could be:

• to represent unconscious desires or wishes

• To interpret random signals from the brain and body during sleep

• To process information gathered during the day

• To work as a form of psychotherapy.
