Only have sexual attraction when I'm asleep?

Throwaway accoount because I'm embarrassed.

I've been pretty comfortable in my asexuality for a while. I'm extremely sex averse and I'm probably asexual due to trauma or body dysmorphia. But I have really sexual dreams, and I wake up feeling like I'm missing something. I don't know if its my subconscious trying to tell me something. Do other people experience this?
