What is the definition of Concerns Macabre?

"Concerns macabre" is a delightfully morbid term that basically means having a rather spooky worry about something, often something that's not exactly creepy but still gives you the creeps. It's like when you hear a faint whisper in the dark, but instead of being a ghost, it's your brain playing a prank on you.
