post edit: Sorry for the length...bored at work.
I have a few experiences...nothing earth shattering, but interesting nonetheless.
First, a story that is not my own.
My friend's grandpa died awhile ago. I don't think he was very old when it happened, maybe 7 or 8, but he can remember it. His grandpa was very abusive to his mother and she was not all that fond of him. After his funeral, my friend's mom went to the cemetery where he was buried to take pictures of his grave. Not sure why she was doing this since he was, apparently, a right bastard, but there she was. She had her camera set to take 3 pictures in rapid succession and she took those sets of three from various angles. After she had taken them, she went to get them developed.
When she got them back, she noticed something strange. In a few of the pictures, there was a dark figure standing 10 feet and to the left of her dad's tombstone. When she was there at the time, there was no one in the area. She took these pictures in broad daylight and this figure was completely shrouded in black. The creepy thing was that he was appearing randomly in the rapid-shot photographs. He wouldn't be in the first shot, would be in the second, then not the third. The creepiest thing was that, according to her, the black figure resembled her dad that had just died.
She still has these pictures and I've seen them and it sent chills up my spine to see them, since it was definitely a figure. He had no visible features and there was no explanation why someone shrouded in that much black could appear that way in the middle of the day in a cemetery.
Now for my own experiences.
Set up: I live in a very old house. We moved in a few years ago, upgrading from our old house. The house itself was built in the early 1830's and is semi-famous in the town where I live. It is three stories tall with a turret on top that you can walk up into from the third floor. Since it is so old and has been preserved with the idea of keeping the house as close to the original design as possible, when you walk through it feels like you're stepping into a Victorian style house in the 1800's. Obviously we've updated it to look newer in certain areas, but the majority of it feels "rustic."
People who have lived in the town for awhile have dubbed it the "haunted mansion." Mainly because, from the outside, it looks haunted. Big, creepy looking house. But for a period between 1950 and 1975, it sat abandoned. Kids would go in there and play in the empty halls, trying to remain inside as long as possible without freaking out and running outside. Eventually the owner before us bought it, completely refurbished it, and made it look how it is today.
The creepiest thing to me is that the house used to be a tuberculosis sanitarium. It was a temporary medical hospital during the civil war and back when TB was rampant, they designed rooms for these people so they could give them food and water without having them near other people. They did this by cutting circular holes in the doors so they could pass food and water through. There are three doors in the house that have these...my rooms have two of them.
Occurrences: Let me start off by saying that I used to be a big believer in ghosts, but as I've gotten older and my views have changed, I've become skeptical. But a part of me wants to still believe.
The first thing that comes to mind was back when we hadn't fully moved into the house. It was entirely empty save for a few furniture items on the first floor. Our third floor was renovated a long time ago for insulation purposes and the stairs that were once previously open were closed off to keep the heat contained.
Before I lived there, as I climbed the levels, my level of anxiety grew. The second floor made me more anxious than the first, and by the time I got the third floor, I felt like I was being watched from all angles. When you walk into the third floor, you walk into a long hallway that has a door to your left that leads to the turret. The closer I would get to that turret room, the more apprehensive I became. I'm not sure if the renovation has stirred things up, but that feeling of anxiety near that room has never really gone away and I've lived there for three years.
The first thing that happened to me happened a couple years ago. We have a fenced off area that splits our back patio in two. We have one door that leads to our driveway and one to the other side of the patio that we let our dogs out into when they want to go outside. I came home, let my dogs out of their dog room, went to the patio door and let them outside. I closed the door, bolted the door, and walk into the kitchen. I get something to drink, stand around for a few minutes to let my dogs run around a little bit, then go back to the door. The door is wide open and the dead lock is still thrown outward.
I would've chalked this up to the deadbolt not being thrown all the way to the locked position, but the lock doesn't make a click sound when it's not fully thrown. I KNEW that the lock had clicked because it turned all the way to the lock position and made that click sound. I even tested it to make sure it was closed because it's just something I do out of habit. When I went to the lock and checked it, it was definitely thrown all the way to the left. Creepy stuff, but nothing that can't be rationalized I guess.
The next time happened a little while later. I was on my computer in one of my rooms. The door to the hallway was to my right. I was listening to music softly when I hear some footsteps in the hallway outside my door. I hear the door knob rattle (at least I think I did), and then the door slowly swings open by about six inches. My first thought was that my dad had come home from whatever he was doing and wanted to see what I was up to. I say "Hello," but nobody answers. I say hello again before getting up to see who was in the house. I go into the hallway, all the lights are off. Search the second floor, nobody is there. Go to the 1st floor, nobody is there. We only use the third floor for parties since it's an old ballroom and it's always hot or cold depending on the year. Not even my pets were anywhere to be seen so there is no way they could have pushed it open. But even if they were there, the door was latched.
The last thing that really stands out is the creepiest of them all. Before I blocked off the tuberculosis holes, they didn't really bother me. It was something that was interesting, a little intrusive as far as privacy goes, but as long as the hole to the outer hallway was plugged with a towel, I was fine.
Whenever I would sleep, I would close the connecting door between my rooms. That door is one of the doors that has the TB hole and the primary reason I closed it was to keep my window A/C's coolness in the room where I'm sleeping, as well as blocking out the ridiculous amount of random lights from gaming systems, computers, and the like. Before I nailed a board over it, the room was so bright that I could very easily see into it from my darkened room. Over the course of a few months, I would randomly wake up in the middle of the night to absolute darkness. This didn't make alot of sense since there was always a bluish glow coming from the hole in the door due to all of the LED lights in the other room. To be in complete darkness was unusual. However, since it was the middle of the night and I was groggy, I never thought much of it.
However, things started to get to me after awhile. I would be about to fall asleep on certain nights and I would perceive absolute darkness for a second or two from my closed eye lids. When I opened my eyes, I could see the glow. One time, I came home after school and closed my door to take a nap. I had all of the lights turned off in my room, but had a lamp on in the other room. I had my back to the door, my eyes weren't entirely shut, and something blocks out the light from the other room.
I freak out, whip around...nothing there. I hop out of bed, open the door. Nothing.
I've had random things fall off flat surfaces...but never when I'm looking right at them and I can never be sure if they fell on their own or if they were already teetering on the edge and a gust of A/C tipped it.
We have alot of squirrels and animals that make their way onto the top of our house and make noise, but I consistently hear very loud THUMPS and dragging noises on the third floor...almost like people jumping up and down and moving furniture.
Again...I have no proof for anything ghostly or paranormal, but these occurrences have made me think twice about things.
tl;dr: I live in a creepy house and shit is occasionally wack.
