Is a wet dream where you are fully asleep but have conscious control of your dream, but don’t know your dreaming a sin?
Well, you may have thought you had full conscious control, but the fact is that you can feel as though you have control and can do something brash in a dream because you don’t have the same thought process as when you’re awake.
I’d say no, but ask in confession to be sure. I’m pretty sure the priest would say that it couldn’t be more than a venial sin.
If you are asleep, you cannot deliberately consent. That’s not a sin at all.
If you are asleep you do not have conscious control over a dream.
