Dream About Skiing Uphill And Finding Pet Snake On Balcony

I was skiing, and I was supposed to be skiing uphill, which was hard, but I actually did it after all, and we went to a conveyor belt that took us to a children's play pit. In the children play pit and I figured out that I can't get out any way, before I thankfully found the exit. After that, I suddenly appeared at home, where a lot of my family members were, even grandparents. I remembered that I haven't fed my pet snake in a long time (I don't own any pet snakes in reality) and I realized that I had it living in a terrarium on the balcony. I went to get it and check on it, and it was alright, and even had a new pattern on its skin. It was turning from white to pink. It survived because its terrarium had worms living in the dirt, and there was water that rained into the terrarium, because it didn't have a roof. I woke up slightly confused, but also happy that the dream turned out alright. I don't know why I have some things repeat in my dreams, so that makes me feel a little strange...
