I saw null (sorta)

Ok. to start off im not trying to clickbait. i never saw him in game, but i did see him while playing the game. its a long story.

Ok, so here i am, playing on PhoenixSC's survival server. 2 friend's online and 2 other people. one of my friends were afk, the other helping me with my new base and the other 2 were doing their own thing. my base is very recluse and away frmo others.

anyways i was just grabbing some more green glass from my trading hall to go back to making my base. i was just movinng around a small hill with the small sheep farm on it, jumped to take off with elytra and i saw him.

let me explain (again)

i play on a school laptop. its an alright laptop. windows ten 8gb ram. minecraft runs fine and i was playing fine. but it has this issue. randomly, it flickers. i dont know what it is. my irl friend says it could be the graphics card or something but i dont know. it happens quicker than you can blink. sometimes not covering the whole screen. usually its like some texturised grey/brown thing or other random things. as i said it happens faster than you can blink so its hard to tell. but i saw null.

back to the game, after i jumped just before i activated the elytra, a full flicker occurred. it coverred my whole minecraft window. from what i could tell from the short time, it looked like null. on the right of the screen, holding a pickaxe, swinging it at the screen, trying to escape. i do not have this on camera or screenshots (as i said it happens way to fast) but i am sure i saw it. i said it in chat after it happenned and they replied with stuff like "that's creepy". i promise to you i am not lying. i persoally know null isnt real (as i said) but this still creeped me out. its like as if null was trying to escape the game.

and for all those people who pay close attention, no i did not take off with the elytra. i experienced a lag spike and landed in the ocean :|
