Dream About Sinking In Water And Lost Mother

My mom and was at some sort of concert or convention. I had to use the bathroom so I got up and went and when I opened the stall door there was water on the floor. When I stepped on it it seem like you could sink right through. I tried to move around the water brut every sto I tried to take made my foot sink. I eventually go back to my seat and mom is no longer sitting where I left her. I then leave the venue and get into this Uber but I don’t go home. I end up going to a man’s house and going to sleep. I wake up and we start to have sex. He stops me while in the middle of having sex and tells me I have to go because he has something he needs to do.
