Is it normal to be raped in a dream?

A few nights ago I had a dream where I was waiting for some kind of appointment and there was a (very attractive) Mexican man with his wife and child. (This isn't me being racist, just specifying. I have always been attracted to Mexicans.) I was working on a puzzle with the little boy, but then the wife and son left, and I went into a hall because I was uncomfortable. The man followed me quickly out of the room and I started running, but he grabbed me and threw me into a dark room. I stumbled backwards and tripped over a box in the middle of the floor that was filled with Legos. They scattered all over the place and I was terrified enough that I was about to be raped, but on top of LEGOS, really? So basically he raped me, and I enjoyed it because the idea of having sex physically forced upon me and being sexually abused turns me on, so I met up with him and had sex with him again.. is it normal to have a dream like this and is it normal to enjoy the idea?
