For the past few weeks, I've been depressed. I had huge friend drama, my mother made it worse, and above all else, I had gained weight and could no longer fit into my clothes. I cried every night, all night, and was extremely suicidal, keeping knives and scarves in my drawers for when I could no longer take my misery anymore. Around this time, I noticed weird things starting to happen around the house. Things like soap dispensers and other items would just randomly fall, and things went missing, only then to reappear in a different place. One time I had a shirt drying in the dryer. I put the shirt in, shut the dryer door, and went back to my room. About two minutes later, I was walking past the laundry room into the kitchen and saw the dryer door wide open, like someone had opened it; I was the only one in the house. Another time, I was at the kitchen table typing on the computer. My mom was taking a bath, when I heard her yelling my name. She got out of the tub and asked me if I was 'throwing stuff at her.' I don't have any siblings, and I hadn't moved from my chair once.
Some days, my lights flicker even if the bulb is fine, or it is a sunny day out. One night, I was trying to sleep in my bed. It felt like my dog was trying to climb in. I got a little annoyed and went back to sleep, but then it sounded like someone was going around my room. I got out of bed, and no one was there; my bedroom door was also closed. I went into the living room and my other dog, Lucy, was in the corner with a scared look. In the middle of the floor she had also peed, which was very unlike her. She hadn't peed on the floor since she was a baby. I tried calling her, but she wouldn't move. By then I was freaking out. I didn't want to go back to bed because I was terrified something would happen to me. So I sat out in the living room... Watching Poltergeist (ironic, huh?) waiting for the sun to come. I kept hearing bangs and clanking in the kitchen and finally, I ran into my mom's room and got under the covers. She yelled at me, and of course did NOT believe me when I said there was a poltergeist in my room. But as I lay down, I kept seeing shapes--black shapes in the doorway. And you know that sound when you hold a shell up to your ear, you can "hear the ocean?" well, that sound was whispering in my ear, and I could literally feel the chills running down my spine.
Since then, I haven't really had any more ghostly experiences. The occasional random clank or light flicker is all. I read online that poltergeists usually hung around in homes where very young kids or teens lived; most of the time the teen will be emotional, hormonal, or going through puberty. Since I am 14, and was very emotional, that poltergeist was the only thing I could think of that would do those things. But still, NO ONE believes me when I tell them the story. They say there's no such thing, and that I am crazy. AM I crazy? Or was there REALLY a poltergeist in the house?!
As for the poltergeist phenomena, I've read this non-fiction book (of course the name escapes me) that may be another explanation to your experience. It was about this adopted girl who experienced the same occurrences you described: things flying off walls and shelves at her, things not where she placed them, etc. It got so bad, they got help from all kinds of professionals, priests, parapsychologists, etc. Anyhow, in short, the activity didn't seem to be from a haunting, but a manifestation of the teenage girl's anger in coping with her relationship with her adopted parents and her own emotions, as per scientists who ended helping her throughout the ordeal. Perhaps you were so distraught, you exhibited some form of this phenomena called psychokinesis, then it subsided once you felt better. Something to consider. Take care! And, again, I hope everything has settled down for you since you've written this post.
