Can dreams tell you stuff about the future?

okay, so i had this dream where me and a friend were just in the mall and stuff and everyone kept telling us to watch out. like one of my closest friends in the dream was a forty foot giant and she was holding a glass of wine and told me and my other friend to watch out. and then some farmer walked out of a store holding a demented dog and told us to watch out. and then EVERYONE in the mall told us to watch out. and then the mall started falling apart.
