Why is it that when you’re sleepy and drifting off, any movement or disturbance can be so uncomfortable or almost painful?

Question

I’m certain this isn’t just me. During the day when I haven’t gotten enough sleep, and I’m starting to nod off, if someone tries to get my attention or I try to move myself or really any disturbance I can sense, there’s a very unsettling feeling I get, like a mini, momentary adrenaline rush, that attempts to jolt me awake. Is there a name for this?

I never thought about it but you’re right. My cat tends to jump up on me as I’ve just drifted off and then I’m wide awake for another hour at least and that feeling of sleepiness is gone. It’s miserable and you’re right it does kinda hurt to start awake like that
