It was either a manhwa or webtoon where this man had dreams of 4-5 individuals but was only able to see their silhouettes. He has narcolepsy which makes it hard for him to be a part of society so he writes books. He has a best friend who works at a nearby restaurant. I also remember he got a new neighbor who cooked for him since it’s difficult to control his attacks and cook without being in danger.
