dream cheating

Last night I dream cheated. My dream was very odd. Carl and I were in Key West with some people that we are friends with and some people that we know, but are not friends with. The girls and I were staying in one room and Carl was staying with some males in another room (included in this other room was his dad). We started the night out together and then split off for dinner. At dinner I ran into Pat McGee. At first we weren't really friends, but as the night went on we continued to talk. All of my female friends were off dancing and left Pat and I alone. We kissed each other. It was a kiss that wasn't necessarily initiated by either one of us; it was one of those movie- both lean in at the same time kisses. It was a real kiss, the kind with tongue, and it was strange. It was so strange because I was very upset in my dream and headed home from the bar alone. Well, Pat decided to tell my father in law that we had shared a kiss. My father in law in turn told my husband, and Carl refused to talk to me. I went back to the bar to try to win him back, but he refused to even look at me. I was still very upset when I woke up, and even apologized to Carl for dream cheating. He told me that its ok to dream cheat with famous people. I'm wondering what spurred this dream cheat to begin with....
