what I think about "Dream"

first of all.. sorry for the various grammatical errors..

I think:
- Not everybody loves to have a dream.
- Dream also can be harmful to a person.
- Dream also acts as a source of creative ideas.
- Dream can be a solution to a problem.
- Dream is a trouble maker.
- Dream can be really nice till a person feels it as reality.
- Dream is too subjective.

and I want to ask the reader,
- What is definition of a dream?
- Is dream same with coma?
- What will you do, if you are trap in your dream?

I really wish for your answer and opinions..
