Here's my ghost story.
So back in 2012 my parents bought an old house. The house was hand built by the owner in about 1930. The guy sold them the house because he was getting pretty old, and his family was scheduling to move him to elder care. My dad talked to him about how the house was built, because we had plans on renovating it and wanted to know where things were placed (piping, electrical etc)
A week later we got the news that the previous owner passed away, and at the same time we started tearing down stuff.
My parents started modifying the owner's wife's bedroom, and that's when the weird shit started happening.
To preface this: me, and my grandma's bedrooms were in the basement, and my little sister's and parents bedroom was on the 4th floor.
The first night :
I wake up because my bedroom light is on, I hear shouting from upstairs. I walk out of my bedroom and see that all of the lights are on in the corridor leading to the stairs. My grandma leaves her bedroom confused because all the lights are on. We both walk to the 2nd floor where our living room and kitchen is, both still confused why every single lamp is on. We meet our parents. They're both very mad, because they have to go to work tomorrow, and they're not sleeping at that moment. Both are also confused to why they got woken up by their bed side table lamps, and the ceiling lamp hanging above their bed.
Long story short: we had to go for a walk trough out the house switching off all lamps.
Dad scheduled an electrician, and a day later we found out that "a brown out could have caused this" even though all switches were physical and not electric.
A year later:
I came home from school and started doing my homework. As I remember it was kind of nice being completely alone in that house, since I got a lot of work done without interruptions.
Anyways, I was doing my homework in the kitchen until my cat sprinted down the windy stairs for the 3rd to the 2nd floor. At that moment she did not care that meant practically falling down the stairs.
Of course this caught my attention because her behavior at that moment was pretty unusual. So as I recall I started petting her, trying to get her to relax, and at that moment I heard a really loud banging noise.
I kid you not the sound is pretty similar to the pipe falling video on YouTube.
Similar, but with a faster beat, 2 to 3 bangs pr second, and that sound was fucking terrifying for my 8 year old brain.
Let's say after that day my dad had to lead me to the bedroom because I refused being in a dark basement.
I don't know where this last terrifying thing fits on the timeline, but i remember waking up from my sister screaming her lungs out. Apparently she was in bed, and thought dad approached her, so she turned around to face him. Nope not dad. It was the previous owner with a knife, attempting to kill her.
I assume this was some sort of sleep paralisys demon but let's say it wasn't fun trying to fall asleep that week.
BTW it wasn't uncommon for us to read a book in the living room and suddenly see all the lamps swinging randomly. I assume it was just a draft, but still.
