What's the stupidest thing you've done in Amnesia?

[Tetrafish]

Going through a door while running away from a monster, trying to shut it but finding I didn't go through the door far enough and just ended up closing it with myself and the monster in the same room.

I guess that can't be helped. What could've been helped was placing too many barrels in front of a monster, having him break them, then waiting for the lag in the game to stop... Some 45 minutes later. This also seemed to remove most of the other objects in the level. Doors, boxes, other various items. Almost everything but the walls and shelves, staircases. Everything else - gone. It was quite weird and I would avoid doing it in the future.
