my dream as a comic

I had a dream last week that a disease was killing the world. The only person unaffected by the plague was Superman, who's a hardy fellow. He went here and there, watching people die, unable to fix it. At the end of the dream the last person died in Superman's arms.

I woke up perplexed at my stupid brain and then forgot about it. So imagine my surprise when I found my dream in a panel of a Dinosaur comic:


Here's what I'm wondering: did Ryan North have this same dream? Is it an old Action Comics cover that North and I both wandered across in our childhoods and subsequently forgot? All I know is, I had to spend eight hours today listening to a motivational speaker, and the notion of a shared dreamlife where everyone dies but Superman is preferable to a conscious world where organizational coaches are permitted to roam the land unchecked.
