About the gravity of this act

[PA_SS]

Impure dreams are indeed not sinful, but in this case, although it is also committed within sleep, there is a certain time when despite conscious of the act, one is truely weak and seems to justify the act out of a seemingly dreamy intention— something that isn't immoral in itself, but the means done by the act is. One couldn't remember what had truely been done at that point, but that the act was done, and done detailedly and consciously, and made out of a stupidly weird intention. It is like within a dreamy state, yet you have been concious and awake of the actions that you made, and even knew that it is sinful, but again, that "weird intention" made it not so. Also, you realized the gravity of what you have done afterwards,
but it is the only thing you remember after waking up, nothing else; that you did that act and you most likely have sinned grievously.

I know that is is a grave matter, but I do not know how to apply full consent of the will and sufficient reflection in this case.

How do you see this? Please do tell me, I have been suffering from the vice, but have been struggling to fight it off for the past 3 months. Thank you!

There you go, there's your answer. Full advertence of the will is not present in the dream state.

Mortify your senses during your waking hours so that your resting mind is less susceptible to these unconscious impulses.

A saint (I don't remember who) stated that we are to ignore our dreams.  Good advice.

I recall a theologian-priest-professor at the Orthodox seminary I attended, very briefly discussing the nature of dreams in class back in the 1970s.
(Apart from the Scriptural/saints' references), he said his opinion was that dreams are to the human mind what defecation following the digestive process is to the human body. "Flush them down the toilet..." was his humorous conclusion of the subject. I agree with his assessment.

The first paragraph is all over the place and difficult to understand.

If you are dreaming, or in a dream like state, that would absolutely diminish or completely remove culpability and the ability to commit a mortal sin of impurity.

It is a yes, or a no.

If you have an erotic or impure dream, regardless of what it results in, even an emission, that is not a deliberate act of the will.

All sin, even impurity, must involve a deliberate act. One must commit an act, or when it comes to a thought or temptation, must deliberate choose to dwell on, accept, and enjoy the thought/temptation.
