Can dreams tell you things you want to know?

Like I saw this really beautiful girl 2 days ago and I really want to know her name and I cant find her on facebook, the reaon I really want to know is because she is the first girl in awhile to follow me around and to take interest in me (i saw her at a theme park) we didnt say a word to each other just stayed close by on each ride glancing at eachother occasionally. But i have been hearing songs on the radio ever since singing lyrics such as "oh shes the one" yesterday and "I was the one, but we split before I had a chance to say a thing" something like that today. Are these signs about that girl? this is so wierd. Will my dreams tell me her name? Im think this could be possible becasue my dads dream did something similar to him of someone he never met (not gonna get into that) but can this happen? I hope it does...
