Why does a small amount of caffeine sometimes make you want to nap and actually make your sleep more refreshing?

There is no such thing as a Stupid Question!
Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.
- ex. How do I change oil
- ex. How to tie shoes
- ex. Can you cry underwater?

I feel like there's different sorts of 'tired', and caffeine only interacts with one of them. I've had some crazy dreams from caffeine naps
Can you described some of these, intrigued
There's exhaustion, which builds up and is relieved gradually with sleep, and is effectively masked by caffeine. Then there's the feeling of incomplete/interrupted sleep; maybe the quality of sleep was poor somehow, maybe you were woken up by an alarm in the middle of a sleep cycle, but it's painful, cognitively debilitating, and sticks around like a splinter in your brain. Caffeine doesn't help it at all, but it can be completely relieved by a nap in which you succeed in falling completely asleep even just for a few minutes, which caffeine does not prevent from happening.
I don't know how much of that is objectively how it works for everyone, but that's how I understand it.
