I build a little walled off shack right on top of a crypt in the swamp. When I try to sleep inside the game tells me "enemies nearby". I take care of enemies, then the game tells me "bed needs a nearby fire". Even though theres fire right next to the bed.

Is it impossible to sleep next to a crypt or am I missing something?

"enemies nearby"

when that happens, sneak for 10-some seconds next to your bed and you can sleep, especially in your troll leather gear.
usually works for me.
