My previous story mentions in more depth my trip to Gettysburg where I was attacked by an evil or demonic spirit, but to make a long story short, something assaulted and strangled me on a haunted bridge while we were ghost hunting. Here is another tidbit on something freaky that happened regarding this trip.
When we came home from that Gettysburg trip, immediately the next day I found myself home alone as my grandmother, whom I live with, had somewhere to be. Something felt very, very off. I felt like something was following me through the house and was watching my every move.
Remembering my assault on the bridge, I was at first terrified that it or something else followed me home, but then seconds later I became angry that my home was presumably being invaded. I ordered whatever it was to leave and told it that it needed to go home because it didn't belong here, this is my house, and the house is under the jurisdiction of God, so it is not welcome here (I was under the paranoid impression that it was the demon from the bridge and thought that evoking God's name would be the best way to make it leave me alone).
Afterwards I felt better and a few hours later was even laughing because at that point I figured I was merely a little shaken after the attack and was paranoid for no reason that something was following me when nothing was actually there.
The very next day, I heard word from my sister that she and our mother were seriously ill and she wanted to make sure I was okay. She'd been paranoid that something was wrong and felt like something was following her. There is a psychic that runs a shop next to my sister's place of work, and evidently she felt like something was wrong and asked to talk to my sister. She asked her if she'd been to Gettysburg recently because a dead union soldier had apparently become fascinated with her after she sang to it (my sister had sung a song to one of the spirits after it asked her to on our ghost hunt, but she told me she never told the psychic this and that her boss was the only person who even knew she had gone to Gettysburg, which is what prompted her to listen to her advice).
She reassured her it wasn't an evil presence, but that it was unintentionally feeding off of her because it had latched onto her out of curiosity. Its presence was starting to sicken our mother as well, likely because she had been on the trip too which drew its attention. She gave her advice to get rid of it and gave her something to help protect her from its leeching effects (she did not charge my sister for any of this by the way, on the grounds that she had sought her out instead of the other way around).
She managed to get it to leave by simply asking it to. It didn't put up any form of a protest or fight, so clearly it wasn't evil as she had been reassured. She and my mother felt better a mere hour afterwards. She hasn't had any negative experiences from this since.
Now that I know this I think something really did follow me home that day, but it left when I ordered it to. I'm glad that I caught it when I did and that it wasn't the demon that assaulted me on the bridge.
