Dreamt I was cutting dovetails underwater

I'm standing in the shop but the floor is river water, and I'm cutting dovetails against the current, every joint coming out perfect except the one I always botch awake. The master is there, not saying anything, just nodding at the water. When I woke up the chisel was still warm in my hand. Odd how the one thing I'm failing at is the thing my head keeps bringing back to solve at night.
