Dreams are meaningless and occur when you aren't awake so you shouldn't spend time trying to make sense of them.
One theory of dreams is that it is the brain's way of discarding things it doesn't believe it needs to store. There is only so much room for information storage up there. But there are only theories. Since you really haven't described the dream, there's not much for anyone, even those who take dreams very seriously as learning tools, and many cultures do, to say about the content, but we all get recurring dreams. It's possible it's related to something that's on your mind, but as dreams are so scattered and drift so much, it makes it hard to connect the dots. As someone who spent a lot of time hoping to be a professional fiction writer, I used to sometimes take interesting dreams I remembered and turn them into short stories, but I can't say I ever found any meaning in them as I remembered them -- I took them and turned them into something else. Perhaps if you write your dream down, it will settle this and stop the need to dream it again -- the brain will be done with it.
