Les Lavandières or the Midnight Washerwomen are three old laundresses in Celtic mythology. In Wales and Cornwall a passerby must avoid being seen by the washerwomen. If they do get seen however, they are required to help wring out the sheets. If they twist the sheets in the same direction as the washerwomen, the individual's arms will be wrenched from their sockets and they will get pulled into the wet sheets and killed instantly. If, however, they twist in the opposite direction, the washerwomen are required to grant the person three wishes.
