Remember holding flashlight up to your hand? Spend an October month with a flashlight and find some magic again.
Hold it up to your face. Tell a story by flashlight's beam.
Go around and flash it at various angles to all your decorations -
How about shadow puppets? Put the flashlight between your legs when you sit down and shoot it up at the ceiling and put your hands in front of it to make shadows on the ceiling.
There goes Casper across the ceiling!
Try a spooky movie that reveals something creepy in the room -
