I have noticed this occasionally on weekends, when the luxury of a nap is more practical. I'll have a small late-morning coffee, feel cozy/sleepy, then nap briefly and wake up refreshed. Seemed crazy at the time. I'd guess you need to feel somewhat tired for this to work (and I am able to fall asleep quickly).
