Another way I’m thinking of representing it is by using dye, the more dye, the deeper the sleep, and see what kinds of patterns it makes, by photographing it, then even making a screen print of the patterns made.
I was thinking, dye may mix too quickly with the water and during the search to find something that doesn’t mix, I found something that was back to basics. How about oil, doesn’t mix, would move in an interesting way. I could then photograph it, cut out the results and screen print the results.
Whilst researching I stumbled across tie dying. This could also be interesting to see how it turns out.
