Are you serious? You cannot control your dreams! My most explicit and vivid impure dreams have occured since I’ve cleaned up my life. Did I experience pleasure during those dreams? Of course! If someone was to carefully put a tiny spoonful of delicious chocolate in your mouth while you sleep, would you enjoy it? You bet!
Upon awakening, I remembered the dream and the pleasure that was associated with it. But I was not proud of the dream and would have preferred that it didn’t occur. No sin here!
That said, I think it is a good idea to pray before you go to bed, perhaps to Michael the Archangel, or the Blessed Mother. Ask them to keep your dreams pure!
Chocolate gags me.
Dreams are not directly in our control because we are not conscious, but we
can affect them. Elements of our day, our fears, and our pleasures are all reflected in our dreams. The mindset with which we go through life and our final thoughts before falling asleep are included in this (if you fall asleep wanting a sexual dream, you’re going to get one).
By changing the above elements of our lives, we can indirectly affect our dreams.
There was a time when I realized just how empty and hollow a sexual fantasy type of experience would be; love is entirely absent, everything is based on pleasure’s pale imitation. This was not when I made the decision to purify my life, this was when I began to understand
why. From that moment on, I completely lost all desire for any sexual fantasy type of scenario. From that day on, I have not had any such dreams.
[Note: my post is speaking about sins of impurity and sexual fantasy dreams, but I believe the following “stages” have a wider application.]
I realized that there are three stages to fighting sin. The first stage is where you know that it is a sin and know the Church’s teaching, but you don’t know why. Nevertheless, you try not to do it.
The second stage is where you now understand and accept the reason behind the Church’s teaching. You continue fighting the desire.
The third stage is where you truly understand the meaning of it. You know the
why and you let go of the desire. I’m having trouble putting this into words. This is a giant leap beyond the second stage.
When I began to understand the
why, I was moving into the third stage. No longer was my conscious self a guard dog restraining this desire to sin (so to speak), the desire was no longer there. You don’t have to fight what you aren’t tempted by.
Of course, all of this is a simplification. Perfection is an asymptote. Our journey is an exponential function, not a stair-step function. When I think of it, I see an exponential graph relating to an RC circuit where the stages I mentioned above are the spaces between time constants.
Of course, I haven’t reached the asymptote, but I did move much closer to it. As such, the desire never
completely goes away (stain of Original Sin evident – I believe concupiscence is the word). Picture an RC circuit after four time constants, that is what I feel.
I believe that there is a point in the third stage where we no longer have such dreams because they provide no pleasure. I believe this is sort of a “coming of age” thing (in the broader sense of growing, not of reaching adulthood).
Having said all of that, I’ve observed that different people have differing amounts of control over their unconscious selves. I have spoken to some who say they have no control whatsoever (heck, some people walk around and don’t know it). I have spoken to some who have said they can control their dreams almost like a TV. They can’t steer, but they can decide when to move on. I seem to be among those with greater control over their dreams. I know that If I fall asleep thinking that it’s important I wake early, I will mysteriously do so (on a fairly consistent basis).
Your dreams are not random images flashing, they depend on who you are. If you change, your dreams will change.
Sorry for the long post, I intended to write a short paragraph.
I think that you are o.k. to receive the Eucharist since this started in a dream. Even if you later realized that you could have stopped, the drive began within a dream and that altered your full consent to the act itself. This may be a venial sin at most. I would mention it in your next confession but I would not refrain from the Eucharist. Dreams that end in nocturnal emissions are usually pretty intense and that is why that happens…teachccd 
That was a capital post, Caesar517. I agree with you, excepting the part about chocolate.
