What does it mean when you dream that your in a different body?

I had this dream that i was in a different body and i had a twin and we had ran away from home and then we didnt have nowhere to go. Then we started talking to this guy that was in his garage and then he took us to an hotel and my twin sister went with him to a room and i waited outside and then like ten minutes later she came out running saying she couldnt do itand she was crying. We had planned to have with this guy for money and i told her not to worry that i would do it. S i went to the room and i told the guy he had to pay me first and he said he was only gonna pay me 20 and i told him that if he didnt pay me 100 that i was gonna leave. He didnt want to pay me so i was leving when he grab me and me.What does thi dream mean?
