I have a bit of a head cold, so last night I took a little medicine to help the cough. I don't know if it was the med or just the head... but I did that thing where I dreamed all night about the same thing! Over and over I worked on a Zentangle ('NZeppel, to be exact!). I woke up and figured I might as well do one in real life, so here it be:
Looks sort of lung-like. Dreaming in Zentangles is much better than dreaming a math problem all night long! At least I know I can do a Zentangle! A math problem, nuh uh.
