a blank dream

Have you ever had an reacquiring dream? where you have the strong sense of deja vu but you still dont know whats going on? and every night you just wake up heart racing and whatever happened in the dream felt like real life? i was in a whitle room. nothing inside except a boy in the corner. i try and talk to him yet i get no respose and the only thing im thinking about is absolutly nothing. my mind is black i cant think.... i cant run... i dont even try to escape, or even know if i ned to im just there trying to talk to the boy. thats the dream. do dreams mean anything? and if they do what would this dream mean?
