Guys I am freaking out , VERY CREEPY INCIDENT

Ok so guys pls comment something that might calm me down because But I am freaking out !

I joined an empty server to farm , and there was another player who was already in it I did the obby and was farming for a good 10 mins when I noticed the other player was no where to be seen I searched the place only to see this player going round and round (not in a stuck manner) Like doing random circles which didn’t look like something a bot was doing , looked like a real human was doing it I tried speaking but the player didn’t reply I farmed for another solid 20 mins This scary creepy player didn’t move their place and was still going circles (not in any order, every circle was different) I tried speaking so much , I stayed for another 10 mins and they still kept going at it

What is happening? Guys it is scaringggggg me 😭😭

NOTE : I AM NOT PRANKING ANYONE PROMISE, I have only 2 devices at home , my tab and my phone which I recorded this from
