White player in a single player game (Minecraft)

Hello everyone!
Today I want to talk about the White player in the single player, in general, yes, I watch one bang, and he flooded survival on vanilla. And there was a lot of all sorts of garbage (only 1 episode came out), and at one point, it was difficult to notice, of course, but you can, the silhouette of a white skin appeared, completely, and this of course scared me, and I wrote in the comments. If you don't believe me, I'll attach a screenshot about the behavior of this white player, he completes buildings, puts torches, breaks blocks behind the player, most often a block of grass, or the grass itself. Blocks disappear, that is, they seem to break but do not drop, but after a while they can be dropped in another place. On the example of the video, when this chelik left the house, the white player broke stoves, chests and so on. And he put a yellow flower in the corner, the strangest thing is that this flower stood on the wood. I honestly don't know what it is maybe this is so pohyp, all that. Maybe it's true. What do you think about this?
