Whats the meaning of this nightmare i had last night?

Last night i had a nightmare! This man was after me he i was walking and he had followed me home and came behind me when i open the door to get in my house then when he came in he starts to act like he is very obsessed with me i told him to leave me alone but he keep messing with me saying i love you and i was like get out my house and he kept trying to pull on me and i ran outside for help but no one was there but i saw my neighbors that live down stair from me and they were just looking and i tried calling 911 and it just a recording saying tell me whats the problem and i did and told them where i lived but they never came so i went back upstairs to see if the man was still there and he start acting very pive again and start grabbing on me and i start to fight him and then i pushed him off the stairs and he felled flat on his back and i thought i killed him and i then i tried to call the police again but it was still the same recording then i just gave up and called my bf and he said he was on the way and he never showed up so when i came back outside the man was gone so i ran and he was just standing there looking at me saying why you running from me in a pive way and i said leave me alone and this mexican lady was coming out her house and when i seen her i ran in her car and she pulled off and she said why is he bothering you he needs to leave you alone then she starts to talk in Spanish and we left and that when i woke up feeling very scared .What do you think this dream is telling me?
