my nightmare

Ok i had a really bad nightmare last nite,and it was the first actual dream i've had in a long time..so i'm really scared..i had a dream i was at hot topic (the gothic store) and i was trying to find something and this guy that worked there asked me if i needed anything and i told him and he started feeling me up..and me and him and one other guy working there were the only one's there..then so i started running and running and i didn't know where i was going..and all of a sudden it's snowy outside and i'm outside running and i hide underneath a brige and i call my mom and tell her i'm under a bridge and i need to get picked up so she says she'll be there in a little bit...then i see the guys again and there above me on the bridge and they see my coat and the guy grabs me and i punch him and run further then the next thing i kno i'm at my landlords house..and i'm breaking in the house cuz i'm knocking and no ones answering and the guy is behind me running and i go into the kitchen in the house and grab knives and come out and start stabbing him yet he's not dieing..so he tells me to calm down..and then the next scene is were watching t.v together..yet i'm still stabbing him and he's telling me where to do it..and while he's doing this the other guy is trying to molest me so i call the cops..and then my land lord arrives with a bunch of friends and they tell me to get out so i throw the knives at the wall and pick up the guy i've been stabbing and throw him out..then the other guy actually does molest me and i start crying and my mom comes and the guys disappear..WHAT DOES THIS MEAN?????????
