I dreamt of drawing pigeons all night

I had a very long dream in which I was doing minimalist drawings of pigeons in a sketch book. I was primarily using a black fountain pen, drawing little detail but trying to get the shapes perfect and exactly like real pigeons seen from a variety of angles. I also used a bit of blue-gray watercolor, very sparingly, just enough to add a suggestion of solidity in three dimensions. There were no actual pigeons to serve as models; I was drawing from memory or imagination.

This continued for what felt like a great many hours. I never got tired of it. I could have gone on for days.
