Experiencing Auditory Hallucinations at Night

I know this may seem scary or unusual, but please be mindful and judgment-free. I have episodes where I can hear what sounds like music and then people talking mainly during night or when I wake up during the night. sometimes my brain turns things like lamps into caged head demons and it can be terrifying. I get these irrational paranoid thoughts that may seem out of the ordinary. What could this be?
