I am 62 years old. The events below occurred when I was 12 through 13. The were so dramatic and real that I remember them as if they just occurred.
My large family was living in a house that was 103 years old at the time. My father was a violent, abusive, psychotic and daily IV drug addict. I had 2 younger brothers and 2 older brothers. The oldest had moved out.
My bedroom was upstairs and to the right. I tried to be in my room as much as possible to avoid my father's beatings. I read a lot, discovered Tolkien and sci-fi. I had an aquarium, chemistry set and microscope. Probably rather like young Sheldon.
Anyway, paranormal things started happening right away. I never saw a ghost or spirit but I felt its evil presence. Sometimes I would get up to leave its presence and other times I would just get up to leave the room for school, etc... I would be stopped in my tracks! I literally could not take a step forward. I never felt hands grabbing me and holding me back or standing in front of me pushing me back. What I encountered was like a force field. You could not push against it like a wall and feel it. It was exactly like the sensation of trying to push 2 magnets together. Just no way to progress against it. Instantly it would fill me with such dread and such a strong feeling of absolute evil that it terrified me. This would sometimes last a few seconds and sometimes a few minutes.
Onetime after getting released by it I started walking down the stairs. About halfway down it floated me down the rest of the stairs and set me down gently. I was shook by that. It was a school day and cereal, bowls and milk were set out on the near end of our long table. I went to reach for a bowl and it scooted 2 feet away from me! I tried again and it did it again. I finally made my cereal. That was the only time that anything manifested outside of my room.
Within a block of my house on the same side of the street were 3 funeral homes. I have wondered if that was the cause of the problem. Whatever it was was palpably evil; like demonic (whether a religious person or not) strong, negative, hating evil. I was so glad to move away from that house.
My youngest brother told me that when he was 10 and home sick alone that a 7 foot lizard-man that felt evil manifested in his room. He had waited 50 years to tell me his story for fear of not being believed. I believe him. He is the type that would rather die than tell a lie. I have seen few accounts of this force field type sensation on the popular paranormal shows and give most credence to those stories.
