Dream About Demonic Creature In Ethics Teacher

My old ethics teacher was a demonic creature, I was in the bath fully clothed, and It came in holding a hammer. I was very confused and tried to get it to leave, but it hit my lower back right next to my spine, creating a roughly ping pong sized hole "that didn't hurt that much, why did you do that..." is what I said, but when I looked back up, it was gone. I looked into the mirror and saw her right behind me in the water. It said "An entrance" and climbed into my back. So I quickly got up and made my way towards my mother into the living room, trying to tell her what happened, but she wasn't acting like herself, so my brain went "maybe she is the possessed one! Maybe it was just a trick to make we think that it's me." On repeat. That's when I heard noise under the couch and a second her speed crawled out from under it towards me. I grabbed her by the hair and pulled it back so she wouldn't come any closer to me, she started crying so my brother (who also wasn't quite right) walked in, then I had a sort of flash idea, that maybe after the demon got into me, she made things look wrong but they might be completely normal and I'm the one acting wierd. I looked towards our balcony, took a running start and leaped of the balcony [5th floor] headfirst, in an attempt to kill myself, but I landed on my feet about 300 meters away from the balcony, completely unharmed. One of the versions of her showed up out of nowhere (probably the demon version unless both of them were demons) she said "good that no one saw you, get back home now!" I put my hand into my pocket, looking for my key, and realized I didn't have it, The Thing that may or may not have been my mother started walking towards the door to unlock it. Suddenly a black haired lady talked to me, I don't know where she came from, but after that I can't remember anything.
