Playing in 20w18a on my java server.
And... Sometimes (primary when i jump down from blocks) my view are twitches into ground level for a bit...
As result, here. I am laying down under "ancient debris" block somehow.
I have no pistons, trapdoors or any mechanism near me or in my inventory.
Environment
Windows 10 64-Bit, JRE 1.8.0_211;
