Goosebumps tend to occur around tiny almost invisible hairs, as the skin tightens around them getting them to stand up. (If we were hairier, the lofted hairs would add insulation.)

The reason this looks more like a rash is that the bumps are "domes" rather than "volcanoes" in profile (gradient curves going in wrong direction). This is an interesting effect, and I think you are on the right track, but you may want to examine some skin for hairiness and see which areas have what density.
