What does my dream mean? *kinda trippy*?

I am walking a trail, as I get to the end of the trail theres a door, I open the door, and it's another trail, I fallow that one and then there's another on, so on and so forth about 10 times, the last door opens on it's own and the is a little 2 year old girl, she looked exacly like me and my boyfriend combined, so beautiful, and she takes my hand and leads me to a carnival and we went on the rides, after we got off a ride my boyfrien stood there smiling, he picked up the little girl grabbed my hand and kissed me on the lips and we walked through yet another door all together. What does this mean?
