A person may believe they have been awake for 13 days, but this is unlikely. When I had my first sleep study, I found out that even though a person might feel awake (i.e. perceive things around them and be aware of their surroundings), they could technically be asleep (as indicated by their brainwaives). There were several "naps" that I took during the sleep study where I did not feel as though I were asleep, and yet I was later told that my brainwaves demonstrate that I was asleep (albeit very light sleep) for certain periods. An "excessively sleep deprived" person (like myself) apparently dips in and out of brainwave sleep all day long (for periods of 5-15 seconds) without knowing.
