Question about Ramadan

Some girl

I am not Muslim and don’t celebrate Ramadan, but I saw a post online today that warned that it was going to talk about death and they weren’t sure if it was Ramadan friendly. I wasn’t sure what that meant as I don’t know much about Ramadan. I tried to look it up but didn’t get any answers, although I did learn more about Ramadan. Would anybody mind/be able to explain what it meant about the discussion of death not being Ramadan friendly as I’d like to learn more?
