I like Dave-W's answer and think his is the best answer you got so far. Now, the Lord has taught me several things through dreams, and scripture does say he will will do this.
You need to get the dream interpreted. I can in no way do that for you I am not versed in dream interpretation, but after I had had a series of dreams. I sought to get them interpreted, because like you said, the dreams had a decidedly spiritual flavor to them and were...different than my normal dreams.
This is what I learned. Dream interpretations are found in the details of the dream. Who's there, what you wear, what color things are, what items are, if you enter or exit a house in a dream which door did you go through and all those sorts of details. Each little detail means something. What color was the girls hair in your dream?
If you have more dreams, write them down quickly so you don't forget the details! Then go get the dream interpreted, or learn to do it yourself. From what they say, dream interp's are kind of cut and dried. You can buy books or google interp lists of what different things will mean in dreams.
I went and got mine interpreted...and then did three things. First I considered the dream interp, in my heart, to dee if the interp seemed to "fit" and make sense to me and my situation in life and the dream. It will either have the ring of truth to it or it wont, for you.
Secondly, I prayed to the Lord to give me confirmation of the interp, because, (who can trust the heart? For it is deceitfully wicked...), right?
Then waited for a confirmation from God to the interp and how I took it and how I feel about it, prayed some more about it...
I think the longest one was three days before I got my interpretation(s). I can't tell you how He will give you a confirmation, He does this in different ways! But I promise you this, you will know it when you get the confirmation. Then and only then you can accept the confirmation. There will be a big lesson in it, the Lord is trying to teach you something! You better listen!

This is where I got several of my dreams interpreted. The owner of the board, a girl named Masterspiece does know how to interp dreams. She banned me because I made her mad when I wouldn't call the police on my kids for (making a stupid decision which affected me greatly), and I chose the high road of prayer and forgiveness rather than having them locked up. IOW, tread lightly because she'll ban you quick if she gets irritated, lol!
God bless her, she was right on the money with my interps and I got confirmations.
What color was the girls hair in your dream that the sexual encounter occurred with? The reason I ask is, one of my dreams was also a sexual dream, and the girls hair color is very important.
You woke up with a feeling in your heart about the dream, that it was a little odd from the norm. I think this is telling you (us), that the dream is significant, the Lord is speaking to you hoping you will listen to Him.
But the world says I have the ramblings of a mad man... Has a nice ring to it, eh? LOL! So don't listen to me. You decide your own path.
