Black screen of death

I had an alarm set today. It went off at the right time, so that’s not the problem. However, my screen was all black. Being I just woke up I thought it was weird that the alarm went off when it’s dead. I tried turning it on and it called 911! Has this happened to anyone before because what the fuck?! It’s very embarassing trying to explain to the operators this. It wasn’t ringing when it dialed and I couldn’t just hang up the phone because the screen was just black. Somebody just answered “Emergency Services blah blah” and that’s when I knew. 😔
