This is the first time I've written anything on this sight. I'm 21 years old, female, and I live in London, UK.
This happened to me a few months ago (can't remember exactly when) but I honestly have no explanation for it.
Our house is rather small, one bathroom and two bedrooms as well as a living room and kitchen. I live with my mum, my sister and my niece. We have lived here almost 4 years and nothing happened up until a few months ago.
My bedroom still has the original floorboards as I haven't got around to decorating it fully yet and our bathroom is directly beneath my room. Our light switch is on a string and when someone pulls it, I can hear it under my floor VERY clearly. Because our house is small, I can hear everything someone is doing in any of the rooms. Anyway, here's what happened;
My mum, my sister and my niece had gone out shopping so I was home alone. I think it was the evening and the daylight had started to fade. I was in my room watching TV and everything downstairs was off like the lights, television and stuff. All of a sudden, I heard the bathroom door open downstairs and the light switch being used (as I said I can hear it clearly because it's under my floorboards) so, thinking they had come back back from shopping, I turned my TV off and went downstairs to see them but as I got to the bottom of the stairs, the bathroom door was closed and the light was off and no one was home. I was still on my own. I have no explanation for it, I heard it so clearly. I even went downstairs thinking they were back and they weren't. I shiat myself and went straight out of my house and sat out there until they came back. I know it's not the scariest story but it scared me because of the fact I absolutely heard someone go into the bathroom and turn the light on.
