Strange noise and then phone turned off

I was watching YouTube then all of a sudden my phone made this weird buzzing sound or alarm sound then it shut off. Is it a sign my phone is gonna explode or die? Lol Just want to know if it's a sign that something is wrong. And if I have to get a new phone. It's a HTC m9 kind of a old phone.

Welcome to Android Central! Did it power on normally after that? If so, is YouTube working normally?
