Depends on the stage of hunger, but I'll try my best:
• Located in the gut area, sometimes reaches up to the chest
• Goal-directed, but kind of myopic: a short vector in qualia-space
• But it's also kind of twisting or shearing into itself, creating a cavity (this gets far more pronounced if the hunger becomes more than mere appetite)
• Energy parameter can vary but is nearly always non-negligible
• Kind of high complexity, maybe a "rippled surface"?
