The endless Bridge and the fisherman

"I was walking across a bridge and I knew I'd been on it a while. Not lost exactly. Just... on it. The other side was visible the whole time but it never got closer. There was a man fishing off the side. I asked if he'd caught anything. He said "not yet" and went back to it. I kept walking. Then it was night and there were lamps, and I realized I wasn't tired. My legs were fine. I wasn't hungry. I just kept going. Someone passed me going the other way. A woman with a stroller. I looked in and there was nothing in it but I didn't say anything and neither did she. At some point I noticed the bridge had no railings anymore. Just the road and the water way down. I didn't care. I walked right down the middle. I woke up and my feet were hanging off the edge of the bed. Pulled them back under the covers. Lay there a while. Got up and went to work and drove over an actual bridge and didn't think about it until I was already across."
