This morning in my dream Water filled the room I was in, and I could still breathe so I knew i was dreaming but I still didn’t control my dream for some reason. What’s this called, or is it a new thing? 
A low lucidity dream. It is a dream in which you know you are dreaming, but can’t control it. As if you understand you won’t be hurt, but don’t understand you can do whatever you want.
Either that, or you just need some practice.
It seemed like to me when I realized it, I was more interested in the dream happening before and just got sucked back in again heh.
