You could kick yourself. Its the middle of the night–or early in the morning, depending on how you look at it–and freezing cold because you, like an idiot, kicked off your blanket in the night. Nearly entirely off the bed, in fact, with only one lonely corner clinging to the edge of the bed.
Sitting up you take it in your hands, feeling that familiar fear from your childhood: that if you don’t find something to cover yourself up, you are leaving yourself open to all sorts of supernatural horrors. You shrug it off with a chuckle and give the blanket a good hard tug, trying to pull it all up with one go.
No luck. It seems to be stuck.
Another sharp pull seems to free it a bit, and you work, tugging it back up and trying to ignore that silly feeling of growing dread. Tug. Tug tug tug…. There! Finally! The blanket is mostly back up on the bed and you are safely beneath it once more, teasing yourself mentally for getting all worked up over nothing. Until, just before you drift back asleep, you feel a tug from that one side still dangling down from where it had fallen before.
Tug tug tug.
