“An accidental nap”.
You know when you’re laying on your couch at home reading a book or watching reality trash on tv? Maybe your head is against a nice pillow… there’s a blanket at hand…?
You didn’t get on the couch with sleeping intent, yet all of a sudden, snoozing simply feels like the right thing to do. And then you fall asleep for anywhere between 20 minutes and 2 hours?
Well my friend, you’ve just experienced a Napcident.
