- As a child I noticed that dark objects against a bright background,
- such as birds in the sky or people or trees backlit by the sky usually
- appeared to have a bright halo around them. I decided this was probably
- an illusion caused by the sudden change in light level from one region to
- the next. Now I can still see these halos, but I have to make a
- conscious effort to do so. I figure this is either because my eyes are
- different (older) now or because the halo is being censored by whatever
- is doing the visual processing.
- This could lead to a situation where somebody goes trying to see the
- aura of a person, and in making this effort the halo appears, the nature
- of which depends on the lighting conditions at the time. A person would
- be unlikely to try to read the aura of a coffee table because they're not
- expecting to be able to do so, and so are not seeing the same optical
- illusion.
-
- Well, it sounds plausible to me....
