People who suffer from synaesthesia live in a state of mixed senses: sounds have colors, touch evokes emotion and so forth.
New Scientist has a brief, but fascinating, look at time-space synaesthetes — people who view time as circular rings in space.
“In general, these individuals perceive months of the year in circular shapes, usually just as an image inside their mind’s eye,” says David Brang of the department of psychology at the University of California, San Diego.
“These calendars occur in almost any possible shape, and many of the synaesthetes actually experience the calendar projected out into the real world.”
One of Brang’s subjects was able to see the year as a circular ring surrounding her body. The “ring” rotated clockwise throughout the year so that the current month was always inside her chest with the previous month right in front of her chest.
It’s not like they’re a humanoid alien perceiving the events of the world through time and space, but still. Experiencing time as a spatial construct is pretty nifty.
