Did anyone else get this terrifying encounter?

[xiao]

I saw the door was still closed and approached it again, thinking it might have been a scripted event. As soon as I got close he roared and banged again, at which point I ran and hid... again

Oh yeah, I think that happened to me too. I slammed the door and ran and then approached it again later and he roared and banged on it again, then later I found it to be open without him there.

Creepy as hell.
