Dreams..

What are dreams? What are they consisted of? What are their purposes? And how do decypher their meanings?

This is a topic long due here but I only decided today to put it on since I only remembered today a few bad dreams I had some few days ago. And I have to tell you it scared the jeepers out of me.

So what are dreams? Are they a sign from God? Or are they premonitions? And how do we know what they mean? Something that really hurts the mind in thinking out what it is..

Is there a difference between good dreams and bad dreams besides the emotional effects we have? Is there a difference between dreams and dejavus?

I have stumbled upon more questions than answers in this specific topic..

If anyone has the answer - let me know..
