When you live in a haunted house, like we do, there's nothing like waking up at 5 am to husband saying loudly, "What the hell is THAT?"
Those are not the words one wants to hear spouse say when you know there's a spirit or spirits in your house, and ESPECIALLY something you don't want heard said in your bedroom.
Luckily, it wasn't the resident spirit(s) this time. It was a little brown bat that had gotten out of the attic and in its fluttering panic, gotten into our bedroom and fluttered around. We managed to herd it back into the upstairs bathroom and into a little walk in closet, intent on capturing it to release outside, but it disappeared. We found the small gap open to the attic that we suspect it flew out of to become trapped in the upstairs.
Ahhh, the joys of living in old houses. Bats we can live with, no problem. It's the rats in the basement that need to be dealt with.
