No. It's not not because you can't control your dreams. You resisting PMO while you are awake may be reflected in your dreams but since you are asleep, you can't control them. Wet dreams ar your body's way of expelling semen. Since your body is used to expelling semen often because of PMO, it may explain your WD frequency. Since you are asleep when they happen, it doesn't count as a PMO issue.
