I dreamed I was a ferry that forgot how to move

I was a ferry, but not the kind with engines or ropes — just a hull shaped like a boat, sitting in the middle of a lake that had no name. The water was still, and everyone who came to the dock just stood there, staring at me like I was supposed to do something. I tried to remember what boats are for, but my memory only held the sound of a child’s voice saying 'I’m fine' after they’d been crying. Then the fog rolled in, thick and warm, and I woke up before I could sink.
