Clearly for better protection against monsters

  It is the only reason. I asked my wife one time why she sleeps under blankets when it's boiling hot (I do not); she said because there might be 'things in the night' so I asked if she thought these sheets will protect her; nope, but otherwise she doesn't sleep.
