The Tuesday regular who vanished

Last night I dreamed I was back on the stand, mid-January, and the pool was empty except for that one man who used to swim for exactly 90 minutes every Tuesday. He was doing laps but his splashes made no sound — just this hollow echo like the water was a recording. I woke up and checked the schedule; he hasn't been in for three weeks. The dream felt more real than the real absence, if that makes sense.
