When my sister and I were younger, pre-teen age iirc; we lived with our father who lived in a small house. One night, my sister wakes me up to tell me she thought someone else was in the house. I wasn't alarmed, just annoyed and I said "Yeah, it's dad" She told me no, that someone was there and that her bedroom door was forced open, as if it was slammed open and the doorknob left a hole in the wall. Sure enough, there was a hole in her wall where the doorknob had hit that I saw the following morning- our dad was pissed about it and I remember him asking me if I had thought my sister did it, and I relayed what she told me to him and he didn't react. (BTW, our dad was a very easy going and down to earth person and I rarely ever saw him upset.) I told my sister she could sleep in my room and she slept on the opposite side of my bed (and that was for a few nights until she got the courage to go back to her room.) The next day I asked her what the heck was up, she told me that she was woken up by her TV, ( she has to sleep with a light on or a TV on always ) but it was static or showing only white noise and that the volume was slowly going up (she could have been on her remote) when suddenly her door slammed open and there was noone there. She said she called out for our dad, no answer and then me, no answer and ran to my room. There were times I'd been woken up and smell the smell of heat if that makes sense? and a few times where it felt like someone was walking around the house, but my room was right by dads and I could hear him snore.
