Day 4

Conditions of tiredness are very confusing. They're non-linear; I was very, very tired before 12 midnight today, but have been fine since then, even enough to read! I've still woken up fine after every nap, but my confusion immediately after each nap has increased. Once I thought that the alarm indicated that I was supposed to go back to sleep. I read someone else report this once. Both Kelly and I have had micro-hallucinations, with varying magnitude. To stay up we walked a lot. At first this tired me out physically, making me want to lay down. But after the next nap, I really enjoyed the walking, and it kept me refreshed. This was very strange, but I'm not complaining.
