Essence monsters trying to escape D:

Found an essence monster in traitor's passage where all the trappeed enemies were running towards me but could only move a tiny amount before being reset so they just jerked back and forward forever.
If i got close they could actually attack and injure me before interacting with the main essence to free them.
They were all "Skitter Golem" monsters.

Exactly the same happened to me.
Here's a video of it
