Closing eyes and focusing on bodily sensations or breathing alters time perception differently than opening eyes and focusing on a distant location.

“If you were to, for instance, close your eyes and not look at anything in your external environment and just concentrate, for instance, on your breathing or the feeling on the surface of your skin-- I know this is starting to sound like meditation, but trust me, it's not meditation-- your perception of time, that is, how finely you are slicing time, would be distinctly different than if you were to open your eyes and focus on a faraway location, say way off in the horizon, and not focus on your bodily sensations.”
