Darklurker

Darkness.. you cannot know what exactly hides in there.. maybe its just a zombie, or maybe its...
== Darklurker or hiding in the dark==
I created a new world on version 1.12.2 . Things were going great, I built a house, found a village and found a good cave with lots of recources in it. 
There were lots of small pits of lava in that cave and I was trying not to fall there, but then, I forgot about pits and fell in one.
I lost all my recources including my bed. The whole minecraft day I was trying to find sheeps for bed, but I didnt find a single sheep. 
It was getting dark, so I had to go home. I decided to wait until the morning, but it was too boring, so I decided to go mine until the morning.
I was mining, I was lucky with recources, I got lots of iron and even a few diamonds. I was going further and further and I was running out of torches.
In a couple of minutes I was in complete darkness, only lava was lighting the cave.
Suddenly, I saw something or someone staring at me from the darkness. It was looking like a player, but I didnt see the skin as it was dark in there, so I decided to come close to it, but it disappeared. I didn't even notice how it disappeared. Maybe was that a zombie? But he would attack me, so it couldnt be a zombie.. maybe he just didnt see me? huh? And then he just walked away? hmmm... So, yeah, I decided that he didnt notice me and just walked away. I returned home, put all my recources into chest and decided to go look for sheeps.
I was looking the whole minecraft day, but.. not a single sheep..
"Allright, I'll just go mining again" - I said and went mining. I forgot to craft torches so I had to go back and make them. When I was going home, I heard sound of someone running on grass, but I was walking. I turned around, but didnt see a single mob near me. It was the moment where I got a feeling that I was not alone.. I got home and when I was crafting torches, I heard running and breaking block sounds above me.
Yeah, I had a second floor. I got upstairs, but I didnt see neither player nor a broken block. Things were getting creepier.. I heard cave sound out of nowhere, but I wasnt in a cave. In several minutes, I heard it again. Some minutes later, when I was going back to the mine, I noticed something staring at me of the woods again, I couldnt see the skin again, just dark silhouette. It could be a zombie, but..its strange, both times it was not far away, so zombie had to notice me. When I was trying to come close to it, it disappeared again and I didnt notice it!
When I was mining, I saw that "something" again, and it disappeared again! I didnt notice it once again..
In the morning, I remembered about the village and decided to look for sheeps again. I came there, but didnt see any mobs. They all disappeared.. "Allright, something really creepy is going on" - I whispered to myself and went home. In the night, I decided not to craft torches, and just steal it from the village. 
When I was getting torches in the village, I saw that dark thing staring at me again. It was in the dark house, where I allready have taken away a torch before. I couldnt see his face, I couldnt see his skin, I didnt understand what's happening.. Everytime it appeared, it appeared only in the darkness. He was always standing in very dark places.. I decided not to tolerate it anymore, so I left the server and have never seen that entity again. Maybe it was a bug, but the only thing I know, it wasnt a zombie..
