Just so folks will know about my "missing time" thing, here's the story.  Ark does a FAR IR sauna about every other day.  Usually, once he is done, I do one too unless other things interfere.  I usually read during the sauna.  I was reading one of my favorite of the romance novels that are part of the current reading project.  My eyes got heavy and I put the book down and closed them.  I drifted near sleep for a bit, then opened my eyes to check how many minutes were left of my sauna.  The timer said 16.   I was a bit surprised because I hadn't actually slept, and it had been something like 37 minutes remaining when I put the book down.  No biggie.  I closed my eyes again at 16 minutes remaining.  Then, I heard Ark; he had come to check how many minutes were remaining, so I looked again too.  Timer said 10 minutes.  I thought, wow, that was fast!  6 minutes just gone!  I closed my eyes again, but was thinking that the time was a bit malleable so I quickly opened them again to look at the timer.  Now it said 4 minutes.  Just gone, like that!  I closed my eyes again and suddenly the beeper announcing the time was up started.  I was really startled at that point because I KNEW I had just closed my eyes.  Ark came in and said "how did that happen?  I just checked and went out, did three clicks on my computer, and now the time is up?!"   So, he was surprised too; I wasn't the only one feeling like time was just a bit quirky.  If it had just been me, I would have written it off as being more sleepy and in a semi-sleeping state and thus, subject to miscalculating time.  But since Ark was also surprised I realized that something strange really did happen thought it was, of course, one of those things that you can never prove.
