How can I figure out why my dog is mad at me?

This is going to sound weird and like I’m anthropromorphising, but I think my dog is mad at me. She’s always done petty things, but it is usually obvious to me why. I have absolutely no idea why this time. While I was asleep she took my vape and buried it in her kennel- her least favourite place. She did not damage it, chew on it, anything that implies she was doing normal dog things. She’s never touched it before, either. She’s a morkie, if that explains the inherent snark. She is also my service dog and didn’t do her task this morning. I have severe narcolepsy and use a Pavlok as my alarm, so it’s set where it beeps loudly 5 times before it shocks me so it can give her a heads up that she needs to make sure I take my pills and get out of bed. My cat noticed my dog wasn’t doing her job and did it for her and I mean, shout out to my cat for being a bro, but like I’m really worried about this.

It’s not that she didn’t do her job because like honestly I’m being laid off and Friday is my last day, so oversleeping doesn’t really matter right now… I want to know why she’s upset so I can make her feel better, idk? I don’t want my baby to be upset
