The exact origin of this short bedtime clip is not documented in the available details, so it is best understood as an internet meme sound rather than a line tied to a confirmed show, film or creator. Short spoken clips like this spread because they are easy to reuse, instantly recognisable and flexible enough for reaction videos, group chats and social posts. Its sleep theme also makes it a natural partner for snore clips and other late-night jokes, which helps explain why it keeps circulating whenever tiredness, insomnia or staying up too late becomes the joke.
