Not technically a dream, even if I am tired enough

So I pulled my leg up to the workbench and started taking it apart.

The insides, of course, didn't make any sense. There were three large gears that weren't connected to anything (including each other) but when they were turned, they turned in sync. A strand of muscle coiled through the holes of one gear, being stretched ever more tightly as the gear spun, never releasing. It wasn't really supposed to do that, I didn't think.

I was able to figure out the immediate problem, anyway: two of the gears weren't touching. I pulled them together and pushed for a bit; they seemed to hold.

I tried to put the leg back together, but the latches wouldn't stick. Apparently some of the tiniest gear-chains (long strands of turning gears that somehow held together, despite not having fixed axles, usually running taut between two parts of the system) had come free and gotten into the latch mechanism itself, which was needlessly complicated.

Eventually what I ended up doing was disassembling the electric motor from my ceiling fan, and using the magnet inside to tease the gear-chains back into place. I never finished; I was still occupied with that when I stepped away for a moment (somehow now having two legs) to deal with the UPS delivery guy dropping off a replacement ceiling fan which was a) the wrong color, and b) stolen merchandise (according to the package description on the pad I had to sign).
