The pigeon Messenger in the cathedral Attic

"I was up in the attic of my current apartment, only the room was massive and had all these grand, arched stone windows like an old cathedral. The floor was covered in scatterings of unread mail and dry leaves. Hundreds of grey pigeons were just sitting everywhere—perched on the exposed wooden beams, crowding the windowsill, stepping over my feet. I had this overwhelming sense that I was supposed to deliver an important message to one of them, but I couldn't remember which pigeon it was or what the message said. I knelt down to hand a bird a piece of bread, but as soon as I touched it, I was suddenly standing inside a crowded subway car during rush hour. Except nobody was talking, and every passenger on the train had a pigeon calmly sitting on top of their head like a hat. Nobody seemed to care or notice. I felt this sudden, irrational panic that I'd left my front door unlocked, and then I woke up right as all the pigeons on the train started cooing at once."
