This might sound a little crazy to you guys. I am not to sure if I had a dream that I am mastubating or if I actually did masturbate while half asleep/awake. I am about 90% certain that it might have been a dream! This is crazy, as it is kind of a situation of remembering that your masburbated yet you do not remember mastubating! I do not notice all the negative traits (Physically tired, blurry eyes etc) I normally have when I masturbate. Bizarre!
I'd say it's bizarre, but I wouldn't count it. When you sleep, sometimes the dreams coraspond to certain outer stimulations outside. I remember when my dream started having a certain song, then I woke to my alarm playing the same thing. I'm guessing your body might of started ejaculating, and the dream corresponded by a dream of you masturbating. You slowly woke up and confused the subconscious half awake dreaming portion with you awake altogether. So all and all, I say it doesn't count.
It happens, man. I remember one time that I woke up in the middle of beating my meat. I don´t consider this a relapse since it is not a conscious activity. And well, since you didnt watch P I guess that is why you are not noticing any side effects.
