I was staying at my grandparents house in Western Australia recently and it was about 11:00 at night. Their house had always given me a feeling of uneasiness, but any odd sounds heard at night could usually be passed off as the old wooden floorboards creaking.
My grandparents had already gone to bed a few hours ago, as old people do, and I was awake chatting away on the internet with the dog resting on my lap. My dog's ears suddenly pricked up like he had heard something and was listening for the source. He then lifted his head, and after a moment, jumped from my lap and ran from the room. I didn't think anything of it. I thought he was just going to investigate a cat that had wandered into the backyard, or had grown tired of me and had gone to sleep in my grandparent's room. It was only when I heard him growling that I realised something was off. I left the computer and went to investigate. I found Woollie, which is the dog's name- in the lounge room aggressively baring his teeth and growling, hackles raised, at what appeared to be thin air. I had never seen him look so terrifying and it made the hair on the back of my neck stand on end. His face was tilted upwards as if he was looking at the face of someone just a bit taller than me (I'm 5'11''). This continued for a few seconds while I asked him, "Woolie, what is it? What is it?", though looking back I don't really see how he could have answered. Suddenly, Woollie caved in at his side and fell to the floor, ending up about a metre away from where he was originally standing and he let out a little yelp of pain. It looked like whatever he was growling at had kicked him in the side, hard. Woollie scrambled to his feet and ran behind me, done with being 'guard dog'. At that point I was terrified, so I picked up the dog and ran into the bedroom I was staying in and closed the door, quickly. After about ten minutes, Woollie decided he was brave again and needed to check the house so I opened the door and followed him. After sniffing the whole entire house he was satisfied that whatever it was, it wasn't there anymore. I'm hoping that it doesn't come back.
The one thing that baffles me about this is that I was always told that demons and ghosts can't hurt you, but they hurt my dog. How do I stop this from happening again, to me or my pets?
