On occasion, dogs will have dreams so vivid that they manifest into actual movement, a physical reflection of what's going on in their sleepy subconscious. Sometimes, it's easy to guess what they're dreaming of; other times, not so much.
In a video uploaded to YouTube this week, a dozing dog can be seen gesticulating in a rather perplexing sort of way, reaching with an outstretched a paw toward the heavens. A person in the clip can be heard saying that he's "petting himself in his dream," but, frankly, that doesn't seem like a very good guess.
So, what on Earth is this dog dreaming about?
