Okay, I've had a few things, though I'm not sure if you'd consider them paranormal.
My mom says when I was just a baby I used to point at the corner of the ceiling and just laugh and smile insistently at something that wasn't there. She thought it might have been a great grandfather or someone who had recently passed.
First was not too long after my grandmother had passed away of cancer. I lived at another house, and my headboard of my bed had cubby holes--I'd always keep my eyeliner and such in them.
Well, one morning, I couldn't find my eyeliner. I had a very small bedroom with wooden floors...not hard to find stuff. I checked under the fitted sheet, springs, everything. Nothing. Came home later that day and it was just chilling right in the middle of the floor underneath my bed...clearly wasn't there before. Little things like this would happen all the time.
Possible demonic/negative force: I was once talking to a friend online who said they were dealing with a dark force in their home. At the time I was a bit skeptic so I said how ah, probably imagining things. They said it had a very sulfuric/rotten egg smell. I thought nothing of it. Well, later that day, I began to smell the same smell. I checked my trash can, checked outside my room, checked to make sure window was closed, checked outside window--everything. It went away, so I thought I was just silly. Next morning, I'm in my bathroom getting ready. Smell it AGAIN. And I felt like a dread feeling. Went away. Go out to the bus stop, in the open air mind you with no sewer etc. Smell it a THIRD time. I'm not religious by any means, but I'm telling you when I got to school I researched so much and even had my religious friends pray. It was gone when I got back, but it's still something I remember to this day.
I speak with my friend on skype who apparently has ghosts or whatever in his home. There would be times when we'd be talking and the tapestry behind him is making a very odd "wave" motion, almost like something is behind it moving across in one spot. I'd say over and over, it's moving, it's moving! But when he'd look behind him, he said he saw nothing. There was no air drafts or anything either. Creeped me out big time.
At the old house and here I'd have a touch lamp that I know I would turn off at night and would wake up and it's on the lowest setting...the cats weren't hitting it and the dog never went in my room. Weird.
My dog will sometimes be sitting in my room and he'll just suddenly stare at my doorway, and his eyes/head will follow "something" all the way across the upper wall until about me, then he just stares. He doesn't whimper or anything, but it freaks me out, as they are no mice or anything in our walls!
The creepiest thing so far that I can't explain is maybe a few weeks ago I woke up around 3 or 4AM out of a dead sleep and I felt terrified. Like, I felt like there was something in front of me (laying on my side), but I couldn't see anything, hear anything, it was just this "feeling." I couldn't speak, I could move so I know it wasn't sleep paralysis, but something obviously woke me up and my heart felt like it was going to burst out of my chest it was so scary and surreal.
I want to say I think I remember this happened once at college too after my grandma died, but I woke up suddenly with more of a warming presence, not the terrifying one I just described.
Oh, and once in a while I have strange dreams that contain either of my deceased grandmothers in them. Like, a few days ago, I still remember because it was soo weird, that Theresa Caputo (Long Island Medium) was in my dream and was talking about my grandmother and things only I/gram would know. And even though my grandmother didn't appear in my dream, it was obvious her presence was in the dream, if that makes sense. Idk, just weird stuff, man.
My mom and sister have experiences all the time (they live in SC), my sister even thinks she has a friendly ghost that follows her. Maybe it's "in the family," haha!
My sister worked at an office that was known to have a haunted boy in it. She forgot her key card once and was trying to find it when the door opened for her. She'd feel him when she worked, and knew he liked Elvis. She'd be vacuuming in the office and the plug would be pulled out when there was still plenty left; the radio would come on and it would be Elvis songs every time.
My mom was at work and said she woke up one night to see a man in a late 1800s/early 1900s attire, top hat and all staring at her; when she blinked a few times, however, he was gone! She found out a man in that time period had hanged himself up in the bathroom.
This one is VERY creepy, in my opinion: My niece had a grandmother on her dad's side who was brutally murdered, but she had no idea at the tender age of 4, nor had anyone else as they were sleeping. My niece and my sister recall her coming up to sister and telling her that "Grandma said she's going to be ok." My sister asked her what she meant. She said--again at the age of 4--"Mommy, she's bleeding all over and she said that she's not in pain anymore." Found out the next morning that her grandmother had been beaten to death by a robber with a bat. Gives me shivers just typing about it!
So, I'm not sure if you'd consider these paranormal or just cooky, haha, but please feel free to comment!
