What Are Dreams?

Dreams
Are dreams our psychological television?
Are dreams adventure stemmed from your imagination?
Are dreams just our self conscience expressing itself?
Are dreams memories from past lives?
Are dreams messages from greater beings?
Are dreams nothing but colors and sounds?

Why do we dream?
Do we dream to cope with our past or present pain?
Do we dream to create hope?
Do we dream to stay sane?
Do we dream because we need to?

Who dreams?
Do you dream?
Do I dream?
Did you have a dream?
Why do you dream?

Can I dream anymore, from all of the horror I have seen, is there anyplace I can psychologically hide from my pain?
