Voices in my head

Sometimes I can hear shouting and screaming in my head, it sounds like a million different people arguing at one time and I can't make out what they're saying. Then it's like my adrenaline starts rushing and my own thoughts get jumbled in with the shouting and they become louder and louder. It lasts anywhere from a minute to 10. I have to calm myself down and make it stop and it slowly just quietens down and dissappears. I've had this on and off for a few years now but it's starting to concern me.

Has anyone else had this? Or have any advice?
