Footprints in the Sand

I dreamt I was walking on the beach. I looked back, and there was only one set of footprints.

They were dog footprints. I asked the lord, "WTF?"

He replied, "That was my dog, carrying you, or perhaps another dog, though, in a sense, they are all my dogs. Either that or you make dog footprints instead of people footprints. It happens."

"Really?" I replied.

"Sure, whatever," said the lord. "I wasn't there, I was making lunch. Tacos. It could have been my dog, or a different dog, but you could make dog footprints. I really don't know."

" Taco?" asked the lord.
