Is it normal to have intimate dream about cousin?

I had an intimate dream about my male cousin last night.. It started out normal with the family in the living room but then me and my cousin escaped to my bedroom where we began to play video games and watch tv and talk.. After awhile we stopped and he pushed me on the bed and kissed my lips.. He rubbed his hands all over my body and I actually enjoyed it and could feel everything that happened.. I told him to wait and i'd be right back so I went to the bathroom then when I was finished in there I walked back to my room after my mom asked "are you two getting along?" and I replied "Yes very much." The moment I got back to my room I got my money jar and I gave him some money and told him if he wanted to have sex with me that he would have to go to the store right now to get some condoms... and he did.. then he came back and we began having sex and it felt so good.. I don't know why but I really liked it.. I can't help but feel turned on but also feel so ashamed at the same time.. Is this normal?

P.S. I'm female -(ALSO forgot to mention that i'm 21 and he's a little older (by 2-3 years) and he's my 2nd or 3rd cousin)) - and my cousin is really tall and attractive and we aren't super close but he does talk to me when he sees me at family gatherings.. but I don't believe I would ever do something like this with him..
