If you have the Mirror for your farmhouse, gaze into it at midnight. Normally you'll be told
it's late and you should go to bed, but occasionally you might have something spooky
happen. You can figure out when it's exactly midnight (0:00am) by going into your farmhouse
and checking the clock. There is also a Mirror in the Town Cottage (the 100 million house)
but nothing happens at midnight.
