Since childhood I've had this recurring dream that I reach the court without my tennis racket / balls / shoes. Then I return to get them, and I get lost or can't find the court, or get on the wrong bus, etc.
Or I am changing buses and leave my gear on the previous one. Now this has never happened in real life, and I haven't ridden a bus in 20 or more years.
One repeat dream that is actually enjoyable is that I am playing fantastic tennis, beating everyone but sadly it doesn't last long.
They never see you coming, do they, Tom ?
