Is dream a form of vision?

Had a very bad dream this morning. I don't consider it as a nightmare cos there is no scary scene in the dream; just that the outcome is not a desirable one...everything is colorful and very real...but I do not hope that it will happen. There were times when what I dreamt of will be realised in months, or a few years time. I think some of u shared the same thing as I do. Though pple may say dreams are the opposite of reality but for my case...not really...hehe...

I wonder if my dreams are visions that HE wanted me to see....
