After a long and arduous fight with a young dragon, we found ourselves at an abandoned hunting cabin and promptly decided to fall asleep without setting a watch.
DM: <Swashbuckler>, you wake up to the sound of something rummaging around underneath your bed.
Swashbuckler: Oh, shit. Ok everyone, wake up!
When we look, some planks of wood underneath the swashbuckler’s bed have disappeared, leading down into a dark tunnel.
Fighter: Should we… Do something about that?
Wizard: I don’t really want to.
Cleric (me): I mean, we need to keep an eye on it. Guess we need to set watches, then.
The rest of the party goes back to sleep, leaving my cleric alone on watch, until…
DM: <Cleric>, you hear the sound of something rustling behind you.
Me: I turn around and look under the bed.
DM: You see some of the wooden planks have disappeared there too.
Me: Okay. I yell “WHOEVER IS DOING THAT HAD BETTER STOP. I’M A CLERIC AND I’M PRETTY PISSED OFF.”
There’s a sound of dice rolling, and–
DM: You see the wooden planks get shoved back into place.
