The peasants of Bosnia often prefer to sleep all together in one bed, clothed, for the sake of warmth.
This unfortunately is one of the ways in which endemic syphilis, which spreads easily on simple contact, is quickly propagated. One member of the family may have become infected elsewhere, and may infect all the others in the communal bed.
