wet dreams typically just happen.

but, eh, you might also be rubbing it out if you’re not quite fully asleep. a lot of weird stuff can happen between waking and sleep.

Your body is paralyzed for the most of the time you sleep so that you don’t physically act out your dreams, so probably not.

Typically, automatically. But, you might be an outlier.

It is rare but possible to go all the way to erection and ejaculation without any contact or repetitive motion of any external kind whatsoever. Some dreams can be bizarrely effecting in that way.

I might have a stupid answer but like what I’m thinking (I’m 100% just guessing) is that you still kinda move around ( like rolling from side to side or scratching your ass ) when you sleep. So therefore, maybe your brain is probably somewhat active - like you are doing more than just subconsiously breathing and sleeping like a dead body. Thennnnn, maybe you are stroking it or maybe its just your brain sending signals to your thingy with out you stroking it. Maybe it’s all in your head.

However, if you’re pumping it then I am sure you would notice it and wake up. Im saying all this because I recently had a dream where I was in a fight and i literally kicked the wall next to my bed as hard as I could. IT FUCKING HURT. I aimed for his neck…

Only one way to find out. Cock cage.

It’s possible. You could constrict your hands somehow to find out.

I would also warn that, if you do anything in your sleep like this that is atypical of sleep, you are probably not getting a good night sleep internally.
