Dreamt last night that I was in a race, it was only masters. And it was in a mall, or a stadium - we were running up and down stairs and corridors... and partway through my right leg was stuck in a 90 degree angle, like my knee couldn't unbend, and I couldn't put my right foot on the floor. I started hopping down the stairs. Then someone in the crowd (why was there a crowd?), yelled "point your toe down", and it worked, and my leg unlocked. Crowdsourcing solutions right there.
