It may be possible. Here’s why:
Basically, if we view the brain as a single point of electrical output, and look at the frequency as the subject’s degree of stress and the inverse of that stress as the subject’s perception of time [read my post on sleep for more detail]. Essentially, the slower you can get the resting brainwaves, the less perceived time will pass. The slower “delta” waves the better.
How do we accomplish this? Deprive the senses. People deprived of light, sound, and human interaction, have gone down for a “quick nap” and slept for thirty hours. The lower the external stress, the further they can travel in the same amount of perceived time.
