Dream of girlfriend

I dreamt that I was at my girlfriend s parents place but she wasnt home. Then one of her brothers called me and told me she moved overseas to teach, but then she walked into the room right after. Then we went to her room and she changed into other clothes in front of me, she was wearing matching pink underwear, after she changed we were going out, but her stepfather was acting weird but there was someone behind him with a knife, so I started chasing the guy. Next we are in the car and my girlfriend is driving but the check engine light was on.
