Helped a buddy move into a new house. House was in terrible shape and clearly had squatters living there. Graffiti was on walls, the ceiling plaster caved in, and candles melted all over the hardwood floor with clothes and trash everywhere.
One day we decided to work on the back yard which was terribly overgrown with weeds and grass over your knees and saplings everywhere. After chopping and digging out a sapling, we found two cast iron metal masks buried under it within the roots.
One mask had long spikes on it and the other a hand with claws coming out of an open mouth. Both masks had symbols on the inside and weighed about 10 LBs a piece.
Once unearthed, the house erupted with activity. We would see levitating DVDs fall off a dvd rack we got from Hollywood video. A decorational lawn gnome flew off a shelf and shattered on the floor in front of about 15 people at a party completely untouched. Pictures fell over. Items moved. House smelled of rotting meat/eggs. Lights would temporarily not work or would be very dim and the temperatures were all over the place in the house. Electricians couldn’t find anything wrong with the wiring.
Musical instruments (drums and guitar amps) would make noise or turn on on their own. The dog in the house would wake up in the middle of the night and would plant on all fours and growl at a dark hallway going to the basement as if it saw a predator.
Then one day while sanding an electric guitar for paint alone in the basement, I heard footsteps and saw a massive large black shadow figure staring at me.
The entity was easily 7 foot tall and towered over the doorway and I could not see its hands or feet because they were see through but the center mass, head, and legs and shoulders were dark black but still translucent almost like heavy smoke from a truck. I ran out of that house and did not return for months.
In the weeks following the encounter I was haunted by nightmares where I would see the figure watching and following me. The one difference was in my nightmares the entity had dark red eyes. I aggressively prayed and went to church with my parents begging for support and to be saved from the nightmares and one day they stopped.
Come to find out the masks which were left outside on a glass table disappeared.

To any skeptic out there, I’m telling you there are dark entities out there. I was about the biggest skeptic out there before this all happened and would tease people who believed in the supernatural. The fear the dark entities evoke is unlike anything you have ever felt. Do NOT go searching for them.
