"Q: Can monsters spawn inside my house?

A: I have yet to see monsters spawn in my house, but I have a basement that leads to a cave. Monsters can and will spawn in a basement/cave, although it is commonly thought they spawn only on the surface."

As far as I know, monsters can spawn anywhere where there is dirt wall. I made a dirt wall room in my house FOR SOME REASON and was killed by a zombie.
