Sheba and the Ceiling Fan

Last night, we had a power failure. About 5 minutes later, Sheba the Destroyer started freaking out, barking and looking up at the ceiling. We figured out that since we've had her, the fans have been running and she's never actually seen them. So last night, she saw this huge propellor like spider thing on the ceiling and went a little apey. She wouldn't walk under it, and she was giving the floor underneath a wide berth.
When the power came back on, she forgot all about it.

Tomorrow she's going to the vets to get spayed.
