It's happened since I was eleven. I did some stupid stuff and attracted a ghost (too long to explain, haha). Long story short, there would be shadows (that shouldn't have belonged there), I'd have that horrible feeling of not being alone, etc. Keep in mind that I wasn't on medication, and I was considered a mature child... Well, for the most part.
Then, it happened again a year ago. This time, a little worse. The shadows weren't as present, but I'd see them in the corner in my eyes or in front of me. Things would move by themselves (again, in front of me) near where the shadow was. It couldn't have been the wind/vent because the windows were closed and the movements weren't near a vent. Light bulbs would flicker despite it being a new change. I'd get cold spots, the sensation of being stroked on my cheek. One time, I felt a sudden rush of being loved for. But whenever I felt like I was being watched, it was a horrible feeling. It was like I was paralyzed; I was too afraid to move due to the assumption that they'd take me.
How I met them is going to make you think, "oh, you've got to be kidding me. You're a troll!" but allow me to explain. As an 11-year-old, I was obsessed with Creepypastas (horror stories). NOW, I AM AWARE THAT THEY DO NOT EXIST. I went on Cleverbot and started "speaking" to "Ben Drowned", some CP/story (little did I know that it was just the website doing its job. It wasn't actually BEN Drowned, because he is just a story).
Then, things started taking a weird turn soon. Although I am AWARE that Creepypastas do NOT exist and that CB is just a website, I can't explain certain things.
It knew things it shouldn't have known. Very, very specific things/things only my family and I would know. It freaked me out, and it could've explained the shadows that were in my house. Someone told me that the entity was using it as a communication device.
Now, I am also aware that this being was not "Ben Drowned". Something was pretending to be him. "Ben Drowned", who is just a story, is portrayed as evil and sadistic. I did not experience any ghoulish dreams and/or woke up to several scratches on my legs. In fact, it was just an observer who wanted to be known.
WHY WOULD IT WATCH ME? If it wasn't a demonic entity... I know it was trolling me and stuff. It confessed that it was just playing around with me and then left, but sometimes I can feel it despite it being gone. Was it really just a bored entity that watched me for over four years...? Was it a spiritual attachment? I find that I have recently gotten severely depressed (quite suddenly, too. I've always been depressed but not this bad. Don't get me wrong, I'm not blaming my depression on this ghost. It's just a possibility. And yes, I am seeing a therapist).
