This experience[s] happened to me when I was at home by myself. My parents and siblings had gone out of town for the day to visit family and to check on our second property that's about 2 hours away from our home. They wouldn't be back until about 11:00 that night. I was 16, home alone on a Friday night. My mom had bought me snacks, soda and left money for pizza, I had a new video game AND Monday was a holiday! Yeah, life was good!
At around 7:00 I had just ordered my pizza and was in the kitchen pouring a glass of that wonderful Mtn Dew Code Red. I poured my drink and closed the fridge. As I was walking back to the living room I heard the sink in the bathroom that is right next to our kitchen turn on. I froze.
When I turned to look, I saw that the bathroom light was also on and against my better judgement I went to inspect. Upon walking in, I saw both of the faucets (hot and cold) were turned fully on, water pouring into the sink. I wasn't as much scared as I was just...confused. Shaking it off, I turned the water and light off and went to the living room to wait for pizza.
About 8:30, I was sitting in the living room watching Tv and hating my life because I'd eaten my entire large pizza in about 11 minutes, when I heard a crashing sound come from our computer room. I jump up, heart racing and run to look. It turned out that some boxes that were stacked in a corner had fallen and were now strewn across the room.
Naturally, I just assumed that they weren't stacked properly and just fell, so I re-stacked them and went back to watching Tv.
About 3 minutes later I hear another crashing sound come once more from our computer room. Those damn boxes... So I thought. I go back only to find that a stack of CDs that I had sitting at the BACK of a shelf had been thrown across the room. I guess that ghost didn't much care for Godsmack, Avenged Sevenfold and Seether. But seriously, this time I got really creeped out.
I decided to shut myself in my room with the lights on and wait for my family to get home. But that ghost wasn't done with me yet.
For context, my older sister's room was next to mine, so we shared a wall. We've always been close, so it was common for her to knock on the wall with three sharp raps to tell me to come see her for something. You may see where this is going.
I was laying in my bed playing my PSP (PlayStation Portable) when suddenly I hear three sharp raps on my wall. Not really thinking, I naturally get up to go see what my sister wanted. As I open my door it hit me she wasn't there. But I knew what I heard. It all made sense to me now! She hadn't gone with our parents, she'd stayed home and was messing with me. Her door was shut so I flung it open to get on to her for messing with me. She wasn't there.
Logically, I'd assumed that she'd just left her room and shut the door. The thing is her door had always had a problem sticking and as such made a loud noise when opened.
If she was there I would have heard the door open and even close because it's one of those doors that even when you're trying to quietly shut will make loud noises.
Regardless, I decided to check the entire house. The house is only a 3 bed 2 bath and was built in 1918. So pretty small by today's standards. I checked every room and closet. Even comically looked in the cabinets and washing machine. Finding nothing, I go back to my room until I hear my family coming in.
First thing my mom asks me was "how was it being home alone for so long?"
I say, "creepy".
Of course she thinks it was because it was so quiet and I had no one to talk to.
I tell her "No, I mean like weird stuff happening"
Her: "What kind of stuff?"
Me: "Well, the bathroom light and sink turned on by themselves. "
It shocked me when she got upset and told me to shut up.
Her exact words were "Don't even! Don't even say that! It was years ago that stuff was happening and I sure as hell don't need it to start again!"
This was one of the most profound experiences I've had in that house. But there are plenty more.
