Round and Round

Last night I had a strange dream - my mountain bike's front wheel was missing, but somehow I could still ride it - in a normal position.

I couldn't understand how it functioned. I remember puzzling over the question of whether the front brakes still worked. I looked, and the front caliper brakes were missing.

I biked uneasily, on a wheel that wasn't there.

Was this somehow inspired by Eastwood's empty chair?
