I had a nightmare.
I had put some clothes down when out walking, then had to cycle back to get them later.
The only bike I could ride was an incredibly low-slung recumbent trike. The pedals were yellow plastic on what looked like 2" cranks. The chain was so long, running over so many pulleys, that turning the pedals gradually tightened the chain for a second, then the wheels slowly started turning.
The trike was so low-slung that I couldn't see ahead to navigate. I quickly became lost in a maze of rural lanes, only able to manage about 5mph with my feet whirring madly in very very tiny circles. It fell dark, I got more and more lost.
It was a great relief to wake and find it was all a dream.
