I have, as I noted the other day, been getting plenty of sleep the past few days, but I've nonetheless been waking up groggy and tired. I know I have significant sleep debt, but it seems unfair that I'm more tired after getting a full night's sleep than after getting a half night's sleep.
The other odd thing is that I've been having anxiety dreams and nightmares. Mostly related to work, which is weird because I'm in more or less a busyness lull at work--plenty to do, but not nearly as much deadline stress as I was under for a couple of months there.
Even had a (mild) test anxiety dream a few nights ago. My test anxiety dreams have generally been not so bad ever since The Last Test Anxiety Dream some years back, but it's interesting that I do continue to occasionally have them, despite my last exam (as such) having been 15+ years ago. (Just to be clear: last time I mentioned TLTAD, I think someone thought I was referring to the first dream I mentioned in that linked-to entry. I'm actually referring to the dream described in the final paragraph of that entry.)
