Lots of insomnia and broken sleep recently, so most of my dreams are fragmented and unformed.
One image that sticks out was from a couple of nights ago. WhenI woke up I drew the image because it seemed significant somehow.

It was of 4 hands gripping each others arm in a square formation, like in the picture. The hands were gripping nearer the elbow, so the square was wider, but this is the closest image I could find.
Perhaps it has some kind of meaning?
