The dog didn't bark, he just looked at the wall

In the dream I'm sitting in the green room of a club that doesn't exist, and the dog is there — not my dog, some greyhound with one ear down. He won't look at me. He's staring at a wall like it owes him money. I keep trying to tell him about the set, how the crowd was warm for once, how I didn't bomb, and he just keeps staring. I wake up and my actual dog is doing the same thing — looking at the wall, at 3am. I took it as judgment for years. Now I think maybe the wall just has something on it. I'm learning to sit in the quiet, that's all. The dog's seen everything I've done and he's still here
