Frost alerts from the other side

I had a dream last night that the entire allotment was covered with a crop of potatoes, destroyed by a sharp frost. The ghost of William Shakespeare was flying above the carnage telling anyone who would listen that he had warned me to put some fleece down.

When I woke up, turned on the radio (to hear the general election results) and the BBC weatherman mentioned that we may have frosts this weekend. Quite why Shakespeare's ghost feels the need to give me weather and gardening tips is something that I am sure will haunt me all morning.
