Could My Wet Dreams And Waist Pressure Indicate Possible Assault While I Was Asleep?

I lock my bedroom door and have 2 alarms on it if it opens, I have wet dreams sometimes I ejaculate and there is nothing, others I don t ejaculate and a pressure builds up in my waist, and I m a virgin, I think I ve been raped but, I didn t accuse because I didn t see anything, I think I was sleeping
