I had something like this happen to me back in 2007. I was living on campus and spontaneously began dreaming about a guy who lived in another dorm. He wasn't someone I knew personally, I'd just seen him around campus and hadn't even really liked him. But the dreams became so real, and freakishly accurate -- like I dreamed one night that he had a hole through his foot, and the next day he was walking around with a crutch. The most shocking thing to me was that a short time after the dreams began, I was told by a classmate that this guy had a crush on me in real life. He began coming by my dorm room for little things, like borrowing costume make-up at Halloween, and I overheard him asking his friend once what my name was and what did he know about me, etc. The dreams were nightly by then, and I didn't know what to make of it -- it was just too strange. Was there a purpose to the dreams, was I supposed to go get to know him? But we were such different people, and it all felt vaguely creepy, so I tried to stay away from him in real life, even though I did secretly become sort of limerent toward him. And in the end, the dreams just stopped on their own. There seems to have been no purpose behind it. And worst of all, it distracted me from pursuing someone else that I was genuinely interested in at the time, who was interested in me as well.
