sweet dreams

Why people keep on dreaming when they are asleep?

Since i was a child I keep on asking this question, and up until now, nobody can't seem to answer this simple question..

Probably because their mind still keep on working and imagining while their body is at rest.Sometimes when I dream of a very nice dream I wish not to wake up from that dream, cause only in dreams I can be rich, famous and all the things that I want I can have it, but that's only when I'm dreaming.

Focal point: "Keep on dreaming it's never too late, we can not only be a believer but a dreamer as well in real life.."
