Has anyone ever had a dream where they had a sexual or romantic encounter with someone who, in waking life, would never look at in such a way? It worries me because it’s almost my subconscious telling me that I like them.
Nothing strange in here, our SC is just treating our emotions.
If you love someone and think about her all the day long ,nothing surprising if she is in your dreams 
I’ve had this before. Sometimes, I dream about kissing people I don’t know/would NEVER kiss in real life, same with dating. But who knows, think it over, you might have feelings for this person.
I started getting feelings that you would probably call “love” for a girl already in first grade when we ended up in our own private group, she felt very special in a way I didn’t understand back then, I just knew I wanted to spend time alone with her again (very unusual kind of feeling for girls during that age 
) and I know both of us had mutual interest in each other and we liked each other a lot but for some reason we never got together, mainly because I was kind of shy for girls and never responded to her frequent flirtatious behaviour (we basically flirted with each other all the time all day and our chemistry was great, but we just never seemed to take it any more steps further), and we’ve both had other partners.
A few nights ago I dreamed that I was spending time with her, so I think I still have feelings for her deep down inside that could probably awaken if we meet again, although it’s not really something that I reflect over.
I wouldn’t panic too much, if you dream about a situation where you feel attracted to somebody, when you would never do so in waking life. Our dreams are driven by expectation and what is on our minds, it’s somewhat ironic that you could have such dreams, precisely because the thought of such a relationship is so uncomfortable that it distresses you. You start to think about the topic, then react strongly, so think about it more… it doesn’t need to be a positive reaction to make it significant to your sub-conscious. Our dreams seem to me to centre around things which were significant to us during waking life, for good or bad reasons.
I would try to relax, to become comfortable with the idea of a relationship between you and the person that you saw. If you don’t have feelings and it’s just because you react strongly, the dreams and thoughts will go away once you find peace with them. Our minds are inquisitive, I doubt anybody goes through life without having thoughts or dreams which are extremely counter to who they are. Dreams explore many possibilities and may just be that, our mind exploring.
Thanks for all the comments. I just remember something else that happened too, when I saw him he distorted and became muscular and beautiful as if the dream had twisted his appearance to make him more attractive. The feelings felt so real but when I awoke they were gone.
I’ve had those. I put details under spoiler tags because the content isn’t just awkward, it’s reprehensible!
[spoiler]I dreamed once that my mother had a penis, and that she forced me to fellate her. Another time, that I was at a wild party where I enthusiastically volunteered for some sexual exhibitionism: my sister and I would “service” one another on a pool table, while those in the party watched and cheered. Another dream became lucid because one of my worst bullies in high school kept flirting with me.
I think the SC of most people are much more subtle and complicated than simple wish-fulfillment. I had issues with my mother’s micro-managing, and some secrets that she had been keeping about our family’s financial situation. I guess it was such a betrayal that my SC gave it a symbolic scenario that was equally (not identically) intimate in betrayal.
My sister was a real party girl, and that just wasn’t the scene for me. I thought that a lot of the other partygoers made very rude advances, and made joking suggestions that were way out of line, which my sister encouraged, and berated me for not playing along, just so she could fit in. I stood by my personal boundaries, but I still wanted the feeling of fitting in with a crowd of “cool” people, which I guess was why my SC gave me that dream. In waking life, we still make occasional jokes like that (her more than me) but from my end at least I am very confident that I have absolutely no real desire for incest.
[/spoiler]Meanwhile, the people I actually do come to like? That never begins in dreams, for me. It might eventually manifest in a dream, but I’ve never had a dream about someone and then woke up to realize that they might be the One. I usually go to sleep already wondering if they are, for those kinds of dreams.
True, though, everybody’s mind would work differently. But one very common thing that I see, is that the subconscious in charge of creating dreams does not make decisions for you, even for something so deeply hidden as who you fall in love with. That’s probably still checked against all sorts of other mental faculties.
