The Ouija Board

We had great fun, except for a few trolling spirits who promised us every torment under the darkness. We laughed at them all, can't be scared after a few bottles of wine.
'Nite Susan'.
'Nite Fran, don't forget to keep the light on'.
As if!
I woke up in total darkness, my bed above the floor, a huge butcher knife placed across my naked chest.
I want to scream but I can only squeak 'Sue, stop messing about , turn on the light, NOW .'
From the other bedroom, she sobs: 'I can't, I am tied up to the bed'.
