I have a few experiences with the being I mentioned in the title starting in 2012. I have pretty much kept this on the down low except for telling my wife and pastor.
It started as what I thought was night terrors. I'm laying in my bed watching tv and as I turn my head to get my remote I saw a figure in front of my closet. I immediately froze. This figure wore a black hood, but didn't have a white face. It looked like a normal older man, but with an angry/sinister look and a reddish face. I'm only adding this in case of a connection and to give a back story of when things started getting odd for me.
Well after maybe ten seconds or so I regained control of my body and the being disappeared. Fast forward about a year later I'm staying at my aunt's house at this time. I look outside and see this figure wearing a black hood and an expressionless white face facing my direction. It almost looked like it had to be a mask instead of a face. I would put it off as just my mind playing tricks on me until I seen it a few times at my aunt's and at my work over the course of about a year and a half.
Had an experience with my aunt's pomeranian where he seemed to have been dragged into a room and the door slammed shut. He was cowering under the bed, which is abnormal for this dog. It was just me and my cousin in the house and she was in the room opposite the house when this occurred. Not sure if its relevant, but happened during the timespan.
Finally, one day I was leaving for work in the afternoon. As I'm about to walk out of the living room I see this being come from the ground right beside me. Then I smelled wet dog. We had no dog at this time so it wasn't the pomeranian. This scent was extremely strong. I then heard a growl coming from behind me and I can swear I felt something else in the room with me and this being. The being appeared to be pulled back into the ground relatively fast and then the smell went away. This incident was in 2014.
For some reason it is currently on my mind and won't leave my head. I googled what I put as the title of this and found people with similar experiences on this site so I decided to share. I don't know what to make of it. I have had no paranormal incidents since then.
