What Dreams May Come

Pants was sleeping beside me on the sofa the other day as I watched TV and caught up on some knitting. I began to hear intermittent thumping sounds that gradually got louder. Turning in the direction of the sound, I discovered that Pants was thumping his tail in his sleep and his tail was all bushed up to about twice its normal size. He often gets a bushy tail when something frightens him, when he's engaged in some really serious play, or when arguing with one of the other cats. He was obviously dreaming about something. I wonder was happening in the dream that made his tail bush up. He's such a sweetie. I hope it wasn't a nightmare.
