Would this innovative product help kids (details inside )?

When I was a kid I was scared of the dark and often covered my head with a blanket. Alas I couldn’t breathe with the covers blocking fresh air. I was wondering if I could use a snorkel or hole In the blanket to let the air in so I could breathe. I’m thinking it could be for cold apartments in winter as well as for those who are scared of the dark. What do you think ?
