My sister's house has always been creepy to me, and this is not the first strange or paranormal thing that has happened to me in her house. Many family members have heard footsteps on the stairs, had items disappear and reappear, heard things, and seen things. Most people in my family are firm believers in the paranormal and have had experiences of their own, so I grew up on ghost stories, and have experiences ghosts/spirits and the like throughout my life.
This story in particular begins after my sister asked me to house sit for her. She has pets; dogs, cats, and fish that all needed fed and cared for. I arrived at her house after a shift at work. I work the afternoon shifts, so I arrived at her house with my dog and my pillow at about eleven p.m.
I was tired from work, so I quickly fed the animals, and crawled into my sister's bed with my dog, her dog, and her cat. I was laying in bed, scrolling through my phone, when I heard a sound in the bathroom. I looked up through the open bathroom door (it was left open so that the cats could get into their litter box throughout the night.) It was too dark to see anything, but I shrugged it off, because my sister's house is older than dirt, and old houses make noises. Then I heard the noise again but louder, and my dog had stood up and was now standing on the edge of the bed barking in the direction of the bathroom. My sister's dog, which is a lot bigger than my dog, was also growling, a deep growl. I squinted again in the darkness, I still couldn't see anything, but I heard footsteps. I jumped out of bed and turned on the light, and the footsteps stopped, but the dogs were still growling.
I called out to whatever was there to leave me alone. The dogs slowly stopped barking and growling, and they didn't bark or growl like that for the rest of the night or for the rest of the time I was there, though throughout the duration of my house sitting experience, I heard more footsteps, this time on the stairs, small noises, and even the sound of a woman screaming. My brother was with me for the latter and said that he had heard the scream too.
