fear of peripheral vision?
If you look at the bottom left corner you can see something, but you dont know what it is.
When looking at the horse and kids, the horses seem to not want to look at it and are trying to avoid or not be attempted to look at it. Kind of like when someone has a giant mole on there face and you try very hard not to stare.
the drivers represent the artist whos trying not to look to his left and right. He is running away from it while the horses represent his fear and eagerness to not see whatever is on the left or right. The kids represent the normal people while the ones in black are the evil ones that give him the phobia.
sorry im shroomin right now but this is really interestin and thats my theory. Though its probably wrong because im usually never right in life.
*also lookin at rainmans picture and this one, it appears the atist excluded the stuff in the middle.
