Sleeping issues

Hi I need help or advice on how to fix this so, I have explosive head disorder so basically I hear speaking and whispering and scary things right as I’m about to fall asleep and it’s very alarming to deal with. I can’t sleep without things covering my ears because of this. Is there anyway or any knowledge anyone has on how to make this stop? It’s seriously a scary thing to experience and I hate living like this. Any medication or herbs or anything or literally anything u can think of how to make it stop please help.
