Why do human beings dream when they are sleeping? What is a dream actually? How do you differentiate a bad dream and a nightmare? I had a dream just now. Was it a nightmare or bad dre4m? hmm. I think i've always been dreaming about something similiar for quite some time. The dream is something like someone kept chasing behind me, no matter where and how fast i ran, I never seems to be able to get away. All i could do is run and scream, the feeling is freaking helpless and full of fear. And when you woke, your heart feel damn heavy and sour, somehow there's still abit of fear. o.o what happen actually?
