Meh, if you think about a certain thing alot, you'll usually dream about it. Dreams are just part of your mind, they mean nothing.
not actually but as you said the dreams are part of your mind the dreams come from your sub-consciousness the dreams represent what you want not nightmares nightmares are stored in a different section of the brain, the same section where the brain stores what happened on the day so, those monsters and aliens that you tought were fake they're real
