Is this crazy?

I had the strangest dream last night... So, I took a whole bunch of provocative pictures. No nudes, though. But like pics of me in my bra, in my panties, a little bit of underboob, some ass action. And I asked my boyfriend if I could send them to people and he said yes, so I did. My boyfriend and I have somewhat of an open relationship, but it's not just like that. Before I was in a serious relationship, I would have definitely done that, taken pictures like that and sent them to people. But now that I am, I would never. And when I woke up I felt soooo horny, but I had no desire to actually take those pics and send them to whom I sent them in my dream. I've always been the person that really likes showing off my body. It has nothing to do with me being interested in the other person, it just makes me feel good to like... Be a slut? Lol. But now that I am in a relationship I only feel the need to show my body to him and I would feel a bit icky if I sent pictures like that to other people. But before I was in a relationship I definitely would have. Also when I woke up I realized I'm on my period, and that's probably why I am so horny. Anyone have any reasoning behind why I would have this dream?
