What is the underlying reason for dreams and how or what determines who is in them? what are some proven facts about dreams and the content of them?

Noone knows for sure: Freud suggested that dreams are representations of unconscious motivations and thoughts. No one knows for sure why we dream but several theories suggest the attempt by the brain to consolidate and process memories and emotions, clean up clutter in the mind and problem solve. Several brain regions are involved such as the pons and forebrain. Dreams can occur 4-5 times a night during rem sleep.

DREAMS: We all dream every night & don't remember the dreams unless there is a very upsetting reason either because of physical illness or emotional problems. Have a physical exam by a Dr. to know if you have a physical illness. If cleared consult with a Clinical Psychologist with expertise in multiple types of psychotherapy to help you with ZOOM & a Psychiatrist for medication & possible sleep study.
