瑞雪兆丰年
If this winter the wheat is covered with snow (as three blankets), in the coming year it will be a very good harvest and you don't need to work anymore.
"三层被" means the snow; in the winter, the snow can help wheat to keep warm and kill the pests.
"枕着馒头睡" means because the good harvest, you will become rich.
"三层被" and "枕着馒头睡" are the Figurative use.
