When villagers sleep in beds lined up against a wall, some of them (the number appears to be random) will disappear into the wall. They stay there for an in-game day or two and then reappear. Villagers don't begin to suffocate or take any damage, but still appear to coexist with the blocks making up the wall.

Interestingly enough, you can also push the villagers into solid blocks, and they also “fly” around while sleeping, sometimes they just become invisible and the only way to know if they’re still alive is by waking them up.
