Found something called Haidinger's brush:
Haidinger's brush - Wikipedia, the free encyclopedia
Is this the colored lights people are seeing? This seems like a direct hit being that it's the ability to view/see electromagnetic (Energy) phenomenea.
It is also understood that,
"Lutein may also play a role in Haidinger's brush, an entoptic phenomenon that allows humans to detect polarized light"
(I was researching Lutein when I stumbled)
Thoughts?
