This is something that happens to me from time to time since I was a kid.
I would take a nap after lunch, on a day like today. Then sometimes wake up feeling disoriented and depressed. Other times I’d feel fine.
What causes this specifically and why does it only happen sometimes?

Beacuse sleep is complex and loosely understood.
We know that when we sleep a shuffling of memories happen, and depending on what memories they are different hormones are associated with them.
Did you have a good day but have a single bad thing happen? Perhaps that’s enough to trigger adrenaline rush during the shuffle.
We’ve found that when there is memory shuffling happening, that if the good (or neutral) experiences are more common then the negative ones those hormones aren’t as likely to be released.
