I have lived in my apartment for about five years now, and I'll admit that I'm not a stranger to seeing ghosts or experiencing forms of the paranormal but living here, I have gotten more experience than I could have ever asked for.
Five months after I moved into my apartment is when the activity began. I was sitting up in my bed watching Looney Toons on Youtube when, out of the corner of my eye, I noticed that something was moving in the bathroom and, although I tried to get a decent look at it without turning my head, and the fact that my vision was a little fuzzy trying to see this thing from outside the frames of my glasses, I could make out a white blur on the ceiling of my bathroom. After which I turned my head just enough to get a clear image in the far edge of my frames, what I saw was a pale white creature. It had horns, it had wings, but no tail or glowing eyes. It was solid like you or me, it wasn't transparent but I didn't feel threatened by it. The feeling I got was more of curiosity than anything, like it was wondering what I was doing but after that I never saw it again. I have had several girlfriends and other friends tell me that they've seen him/it when they've c.me over though.
About a month later, I was actually on this site reading several stories (just before I went to bed) about new apartments and the new tenants that had just moved in hearing banging noises in the attic and other unsettling sounds. Well, I had just started to doze off when all of a sudden I heard a noise in the attic right above my bed that sounded like the beams and rafters were being snapped in half. I jumped up out of bed, my heart racing. I thought the roof was going to collapse, cave in or something. After that though, I learned never to read anything late at night before bed lol. But that doesn't mean the sounds have stopped!
After experiencing the creature (Mr. White as I call him) and the loud sounds in the attic, things got relatively calm. Granted, I would see a shadow move across the wall or see something dart past me from the corner of my eye, but nothing really disturbing until I watched a movie that fully "unleashed" the ghostly activity in this apartment.
I don't know how it happened, but after watching the first "Paranormal Activity" things just kind of exploded. After watching that movie at 4:00 in the afternoon, something sinister chased me out of my apartment, in which I had to go stay at my dad's house for the night to calm down. Then, after reassuring myself that it can't harm me and regaining my cocky and arrogant demeanor and personality, I went back to my normal routine of life. But since being chased out of my apartment, I have seen the shadowy figure of a little girl next to my toilet, while at the same time a white mist figure of a man casually leaning against my bathroom sink. I have seen the figure of an elderly man in my kitchen, I have heard "protective" growling come from behind my recliner (the same way a dog will growl at someone it sees looking out a window, and I don't own any pets), I have seen a spirit ball the size of a bowling ball on the top shelf in my closet, I have animal spirits of cats and dogs that will frequently visit me (when the cats are around, my general area will smell like kitty litter and when the dogs are around my entire apartment smells like wet dog), and I have learned that the ghost of a 7-year-old girl named Emma has attached herself to me and has been following me for the past 20 years (I am 26).
However, 2 years ago I had a former friend's mom, who is a licensed and registered Psychic/Medium, come check out my apartment. She told me something a little disturbing and unusual. Apparently I am "sharing" my apartment with 2 demons, one is male and the other is female. According to what my friend's mom said, the demons don't like me but they don't hate me either. They like my personality but they are afraid of me and they stick to my closets (which, for a studio apartment, I have A LOT of closet space.) I have never been attacked or harmed by either of them and if they come near me, they behave themselves.
Overall, my bathroom is where practically all of the spiritual energies come from. And I tell you what, it is a shock when you're taking a nice hot shower and all of a sudden there's a cold frozen spike right next to you. But as I said, for some unknown reason after watching Paranormal Activity, the ghost and spiritual activity in the place went from barely nothing to a constant occurring thing.
