Dream About Being Chased By A Stranger 15

me and my sister and her boyfriend were coming to my apartment late at night several nights and there was this man that i kept trying to warn them about but they didnt believe me anyways he was like a heavy drinker, homeless kind of tall, and broad and he was on the side of the road waiting for people to show up and each night we passed he raised his left arm up, and if you looked at him that means he will chase you up until the door of your building and if you overrun him then he will stop and my sister looked even though she wasnt supposed to, and we ran every single night because he genuinely wanted to kill us, and i would often lose pace or trip and fall, but he never caught me and i was so afraid of him and of what would happen if he caught me and a few days later it kept repeating, i came home and saw my sister befriend that man and place him in our house to sleep and eat, because supposedly he didnt have money or family and i told her she was crazy because he is obviously lying just to gain sympathy, and his eyes looked completely crazy, but she wouldnt believe me and just said i was crazy and then i just left
