Every time you visit a coworker, move something around. Move their family photo frame to the other side of the desk. Their mug just a little more out of reach. Tilt the lamp slightly. (Or non-office-from-the-2000’s-specific examples.)
Eventually let them know you’re playing this game with them. But only after they confide in you about “the ghosts.”

This series was inspired by people asking me “How do I keep doing improv?” after a corporate improv workshop. There are, of course, improv classes, more workshops, team building exercises you can do with your group, but these games are specifically ones you can do on your own to practice “Yes and” and get into a state of play.
