Sometimes a person is so boring or unintersting that other people listening to them can't stay awake.
This trope is used to drive home just how boring this person (for convenience's sake, let's call her Sandy) is being. It's often played for laughs, especially when Sandy fancies herself to be interesting or profound. It usually, but not always, occurs when Sandy is delivering a long monologue.
In general, Sandy isn't aware that people are falling asleep on her at first. Sometimes this fact will be revealed to the audience but not to Sandy, so the audience will be clued in that Sandy's words are unimportant. Other times, Sandy and the audience will discover the listeners' sleepy state together (often in the form of a sudden loud snore).
Upon discovering what has happened, Sandy may magnanimously cover her sleepy victim with blanket or tuck them into bed.
Sandy is oftentimes Windbag Politician. Can result in Asleep in Class. Related to Long Speech Tea Time, but this trope is about characters unintentionally falling asleep on the speaker rather than deliberately ignoring them.
This trope is not the same thing as lullaby, which is a deliberate attempt to lull someone to sleep (and thus carries none of the embarrassment for the singer that this trope carries for Sandy).
In Scrapped Princess, this happens when Zeferis tries to explain the reasoning behind her and Natalie's actions against Shanon and the others, and her resulting conflict of interests, to Pacifica who just doesn't get it. This is because her explaination consisted of Techno Babble set to holographic imagery, so Pacifica fails to understand any of it. Instead, it causes her to nod off and fall asleep. Zeferis even has to tell her to wake up so she can repeat it; this time, in simpler terms that Pacifica can understand.

He then goes on to introduce himself, eventually trailing off into a long-winded story from his past. As you can guess, as soon as he gets into the details, the entire party falls asleep and wakes up a couple of hours later, just in time to see Grobnar finish his story. He remarks that you seemed very concentrated on the story, although the sounds you were making were rather strange, almost like snoring...

In fact, at one point, Arthur reads over a draft of one of his letters to Adil, and remarks, "Even I'm boring myself to sleep!" D.W. even cruely remarks that Arthur read her one of the letters he was writing, and it put her to sleep.

Five hats means that five tropers think it is ready to publish.
You are saying that you think this draft is ready to be published. That means the description is not ambiguous,
it doesn't duplicate an existing trope, there are at least three examples, and the title makes sense.
Is that what you meant to do?
You are saying this draft has a ready-to-publish hat it does not deserve and you are taking it back.
