I see future in my dreams?

This might sound funny to you, but i am sleeping and having this dream, and I swear to god in every dream there this one scene that always happen in my future and i always realize its so familiar. Its not like i know its gonna happen, but when it happens i know i have seen ti before happening in my mind. and also few days back in my dreams I had a dream about school and the word Paradox, and next day we were talking about it in my cl for English and i found it very interesting. Anyone like to tell me whats going on?
