A person who has a strong compulsion to stay in bed; sometimes, even after waking up: "Depression, chronic fatigue syndrome, or some other physical and/or mental disorder can cause some people to oversleep and avoid life’s daily responsibilities; however, dysaniacs have a strong impulse to remain in bed regardless of what the consequences might be. They just want to stay in bed!"
"Staying up late watching TV, working on the computer beyond normal bedtime, and insomnia are just three examples, among others, that can cause people to become dysaniacs."
