A couple of days ago, my morning alarm interrupted a very vivid dream in which I had taken a small bucket of water and splashed it out onto the dining room floor. Muddy cat footprints had appeared in the water, though no cats were visible.
Upon awakening from the dream, I went into the bathroom to brush my teeth and that sort of thing, and while I was in there I heard a loud clattering sound downstairs. When I went downstairs, I found that one of my cats had upset his water dish and spilled water all over the dining room floor. There were muddy pawprints, but the cats, presumably having been spooked by the sudden noise, were nowhere to be seen.
The noise made it clear that the water was spilled a few minutes after my dream, ruling out the explanation that the dream had been inspired by sounds I heard while sleeping. (I suppose it’s conceivable that cats knocked down the dish while I was sleeping and then later bumped it again and made another sound. However, I don’t think this is likely. The clatter I heard was very loud and was clearly the sound of the dish falling from its stand to the floor, not just moving around on the floor.)
I’ve been keeping cats for about four years now, but they’d never knocked over their water dish before.
