Dream About Lost Child In Pool

I was at my moms house and she was babysitting a little girl. The little girl missed her mom a lot and told me she was at a school at a pool. My mom told me not to take her and made up some lie about why i shouldn’t take her. I decided to take her anyways. We arrived at the school and it was an old factory type building with a bunch of different floors. I took her inside and she was wearing a princess type dress. We had to go up through a tube which was scary and suffocating and it took us to a pool. The pool was hot, I could tell because there was a bunch of fog and it was cloudy. Coming Up from the water was large water bubble that had a black goo in them, they would hover for awhile and the pop and the goo would go all over. We would get out and have to go back up the tube to get back to the pool. When we were on the bottom floor about to head back up everyone started to say something happened with the pool. I thought about my mom saying that we shouldn’t go so I made it a point to make sure the girl was ok so my mom couldn’t throw it in my face. While going through the school I found the little girl and all I wanted to do was help her find her mom. We had to keep going up these small spaced staircases looking for her mom. We never found her mom.
