Imwatchingyou

Hello, usually I am not the type to write creepypastas, but I was playing Build Battle on Hypixel (like the silly little child I was) a while back and encountered something strange.
I had player visibility off because my computer has a stroke whenever I play games on it, so i didn't want it to freeze, which it has done before.
Despite this, I saw a player.
His skin was a Herobrine template with darkened, unsaturated colors. He was Level 21, and his name was "ImWatchingYou". I was put to unease but nothing more. (He was also holding a diamond sword, but I didn't feel the need to include that)
Another strange thing about him was that every 2-3 seconds or so he would teleport, leaving black particles in his wake. After that, he would turn to face me at a rate just slow enough to creep me out a bit.
And that's all.
He didn't say anything, he didn't react when I hit him, he was just... there.
I have a video of him, but I can't post it online because A. I took it on my phone and B. My parents were talking about political opinion, so I want to mute the video.
Farewell, probably forever.
Post-script: Please tell me if this is an NPC. I originally thought it was a watchdog or something.
