That is to say that certain synesthesiac human beings can see within the mind’s eye an accurate method of measuring time.

The “normal” form of the condition called synesthesia is weird enough: For people with this condition, sensory information gets mixed in the brain causing them to see sounds, taste colors, or perceive numbers as having particular hues. But psychologist David Brang is studying a bunch of people with an even odder form of synesthesia: These people can literally “see time.” Brang’s subjects have time-space synesthesia; because they have extra neural connections between certain regions of the brain, the patients experience time as a spatial construct.

This is quite awesome. I am not certain if this is a sort of illness, disability, or hallucination but my belief is that is a sort of special ability. The curious thing is that all the Comments (at least when I read the article) are all people who are all manifestations of this phenomena. I am skeptical of that; I think some are either fakers or just imaginative.
