I dreamed of a bath-room battle and a doll's embrace

I drempt of an odd dream I've had twice before with a room that was like a bath and I had to do this routine so nothing bad could get out and attack me. I had to collect all the little toys in the water snd get them out, then I had to defeat the monster in the mini room inside that same room and then lock the doors to it, and finally I had to convince the evil barbie doll I was its friend and I had to put it to sleep . Then I had to lock the two entrances to the entire thing and return back to my shower room with the toys I'd saved.
