What’s the difference between 무서워요 and 공포스러워요?

I was listening to a supernatural/spooky podcast and they used the word 공포스러워요. When I looked it up on Naver Dictionary it says a few different things: scary, spooky, horror. My husband (half Korean) says it means “terror” and that he’s never heard anyone use it before but I wanted to see if someone else had any idea? Is there a specific way/context that this word would be used over 무서워요?
