Any thoughts on why a happily gay person would suddenly have several happy hetero dreams?

I dreamt last night that I was getting married… to a dude. White gown, big wedding, the whole deal. It was all perfectly normal and happy during the dream and when I talked to my groom-to-be in the dream, I was happy and had feelings of what a wonderful person he was. I embraced him and told him sincerely that I loved him so much, and in my dream, I did.

When I woke up, I kinda went, Huh. Odd. It even caused me to question my sexuality for a few minutes until I woke up enough and I realized that nothing had really changed for me. I mean, I’m not closed off to the idea, I just find it really unlikely that I will ever be emotionally and physically attracted enough to a man to date and/or marry one.

I’ve had another couple of these hetero dreams lately, though nothing quite as surprising as last night’s. I’m confused and don’t really understand what my brain is up to, cause, ya know, I really like the ladies a whole lot normally.
