I have had multiple experiences with the paranormal before my mother died. However once she died and it seemed the activity picked up with the darker entity that I call the black figure.
My first memory that I can remember of the figure is when I was about 4 or 5 (back when my mother was alive). It would always be me, my brother and my mother who was always in between us and I would sleep on the left side of the bed nearest to the closet and the door. Well my mother had a headboard that had 3 mirrors on it in a row and the mirror above me allowed me to see directly out the door and into the hallway, the hallway light was on just about every night because I was terrified of the dark like most kids are.
I have a hard time sleeping even as a child and while I waited for sleep to take me I would rollover on to my stomach and some way or another something would always draw my eyes to the mirror above me. There would always be this black figure standing in the doorway staring at all 3 of us, and at first I thought it was my grandfather because my grandfather had his bedroom right across from us but it never struck me as odd that he stayed there staring at us.
My grandfather was a mean man back then so my first instinct was to always close my eyes and wait for him to walk away, and I would always fell asleep before I could have the chance to hear him walk away. As time passed I had more and more trouble sleeping and the more trouble sleeping the more I would see the black figure in the doorway and eventually I got so used to seeing the black figure there that every time I saw it in the mirror I would get more and more detail of it but it remained a solid black so I couldn't get any features from it. But I started noticing that it never left the doorway the entire time I was awake and the next morning my first thought (never failed) was "Did I dream that or was it really there". Which takes me forward 7 years (12 years old now) to where I've already had my fair share of experiences and a bad habit of staying up all night and binge watching shows.
One night I was laying on the couch watching some show on tv and I just get this overwhelming feeling of paranoia or anxiousness but I figured I was just sleep deprived (it had been awhile since I slept) so I just wormed my way deeper in to the cushions and pulled my blanket higher as I turned to my side. When I did that I was able to see the sliding glass doors and into the pitch black backyard and the only light was coming from the tv which was bright enough illuminate part of the kitchen. Maybe 10-15 seconds after I had turned to my side I saw a black figure walk across the kitchen and it blocked out the light that was hitting the sliding glass doors. I watched it disappear into the island and before I could let it fully register I told myself "Nope, shut up" and I turned to my other side and drew the blanket above my head only leaving a tiny hole for air. When I told my mom about this she was obviously worried about it but didn't want to scare me so she tried to brush it off and tell me I was imagining things.
A year later when I was about to start freshman year my dad's dad died, then a week later my mother died. Everything went downhill fast and it felt like the energy in the house just became stronger and overwhelming. I feel it resides in my mother's/my old bedroom. I have more experiences with it once I moved out but once I completely cut myself out of my fathers life I have yet to see or feel anything related to that energy (well actually once but it had nothing to do with the dark figure... I hope). My father is a terrible man who has done awful things so it's no surprise evil follows him and his offspring.
What I do is smudge the house, burn incense with white sage in it and also let as much sunlight in the house as possible while in the day.
I feel that they are evil and they feed off your negative emotions but that is still not verified but you do get a feeling of dread when they are near.
