So, my family and I lived in a haunted apartment from 2007 until 2015 (when my parents got divorced and went separate ways). It used to be my great-aunt's apartment until she passed. When we were emptying the apartment, about to move in, we started finding weird stuff hidden in different places. Small bags with stones, hair and pieces of nails, most of them in the room that ended up being my sister and I's. We just threw it away and didn't think much of it. My family is Christian and we don't particularly believe in witchcraft. What I do believe now, is that negative energy can attract negative things.
Through the years we lived there (if you are wondering, my family never had much money so there was no possibility of moving) we experienced several paranormal things but never really talked about it with eachother because we didn't want to scare one another. One of the scariest things that happened to me was the following: that day my mom went out for groceries while I stayed studying in my room. After some time I heard footsteps going to the living room, and the TV turning on. It bothered me so I went and had a peek to see if my mom was there or if she just left the TV on and I could turn it off. I saw she was there, so I went back to my room. After some time, the TV went off.
Eventually, my mom arrived. I asked her where she had gone the second time, and she told me she didn't knew what I was talking about: she hadn't come back until then. I immediately turned pale, because I saw a woman in front of the TV, and I heard those footsteps. I knew there had been someone there.
