What does this dream mean?

Hi. I have a semi-reoccurring dream that's really odd. It's reoccurring in the sense that it has the same theme, but it's never the same EXACT dream. The dream is that I go to this local amusement park...ALWAYS at night and I have it like once a month with different people, though sometimes the same people are in it. It usually ends with me riding the rollercoaster. Does this have any meaning? This is really the only reoccurring dream I've ever had.
