Strange Happenings Lately?

So, a couple of weeks ago I have had some strange happenings in my house. I will tell you. I always hear noises and floor creaking noises in my house its creeping me out when im trying to sleep. Also when its 11 pm and im doing homework and my mom is sleeping i hear a LARGE creak coming from the bathroom. one day when i was sleeping i saw the door and it was dripping down in red blood i think. and i would see a creature standing next to the door sometimes a dark creature. i believe in God and have a medallion of the virgin Mary. ever since i have been sprinkling holy water this stopped. Thank the Lord. also. i have had a dream well more like a nightmare: i saw the devil's face (red and ugly). i started hearing a pounding noise in my ear. and demonic laughter. what does this all mean and how can i stop my fear of demons? pls help and thank you for reading all this.
