what kind of weird swimming pool is this???

Date: 11/22/2016

I don't really remember my dream very much, but one part of it that I remember is that I was with my younger cousins. Ivy, who is six going on seven soon and Michael who is two. They told me that o could go swimming with them in there swimming pool. But really, it wasn't even a swimming pool, it was a lake with a tile floor that they said was 180 feet deep. I could see the bottom still. And there in the middle of it was this black thing, maybe a filter thing that looked like an outlet with blue light coming off of it. Then they took me to a building which was apparently their home. The rest of my dream was confusing and hard to explain using words. But I did see my old friend Alyssa many times. And that is basically it. And yes, I know, it was a little confusing. But aren't all dreams a little confusing??
