Dreams are a way for your subconscious to release any pent up worries or frustrations, and for you to visualize your goals and objectives in life. Everyone dreams, even if these subconscious movies are not remembered when you wake up. Dreams are different from nightmares because dreams are typically pleasant while nightmares are terrifying or disturbing in some way.
You can't realize your dreams unless you have one to begin with
If dreams give you power, then I'm strong enough to walk through my heart till you love me
