Mia is a sleep paralysis demon, meaning she might appear when a person encounters sleep paralysis. She can read minds and is not known for hostile activity, being rather peaceful when she appears, she can talk to people telepathically and prefers doing so over actual talking. Mia, despite quite literally being a demon of sorts with horns and a demon tail, actually has a rather relaxed and calm personality, known to snuggle with people during sleep paralysis.
