Question

Why do we dream?what is dream?​

Answer 1

Answer:

Dreams are hallucinations that occur during certain stages of sleep. They're strongest during REM sleep, or the rapid eye movement stage, when you may be less likely to recall your dream. Much is known about the role of sleep in regulating our metabolism, blood pressure, brain function, and other aspects of health.

Dream is something that we like, that we expect it happen in future... We dream so we will start working hard to achieve our goal we dream off.. (this is not a scientific ans I just wrote this myself)
