Emanating swirls

I am currently working on this piece. At the moment I am working on a collection of portraits of people that emanate strange spirals from the centre, creating a sort of hypnotic mass of entangled energy. Interestingly I read an article the other day about how geomagnetic forcefields in the earth could be the cause for depression and suicide amongst people. It is theorised that these geomagnetic waves (from the core of the earth) can affect serotonin levels in humans and is responsible for about 20% of the causes of brain imbalances. The difference between humans and animals is that they can sense these waves (hence the reason they act strangely before earthquakes) but we cannot sense them. Perhaps the swirls in my painting could be geomagnetic waves infiltrating the minds of my subjects?
I can't stand art that requires a long narrative to go with it...why am I trying to provide and explanation for this? I did it out of impulse!
