I think it's about the few minutes when you do actually sleep, to determine if you have sleep apnea.
I had that, six sensors on my skull, a nasal air sensor, two leg sensors, a stomach and heart sensor, jaw, chin and eye sensors as well as two chest expansion sensors, all wired to a data logger that was hung around my neck and took as much space as a cat sitting on my chest.
Talk to the specialist, my sleep study last week was done at home in my own bed. Went into hospital for an hour to get wired up, drove home and went to bed at my normal time.
My first study was in a sleep lab. It is as you describe. My second study last week was at home in my own bed. The experience was much the same.
As it happens, Lemmy is a person and if everything is as expected, they're still where they were after their funeral service, at the Forest Lawn Memorial Park (Hollywood Hills).
If you're wondering, it's a cute idea but they clearly haven't actually done a sleep study. Being wired up to 19 sensors leaves little room for movement, let alone extracurricular activities.

Cute, but I'd be surprised if that was a real sign at any point in time.
The McDonald's at Yass is actually open 24 hours, and I'm pretty sure that has been the case for at least 20 years or so when I last visited.
That website isn't loading for me.
Where is the 97% going?
As a developer I can confirm that we see all kinds of "stuff".
My most memorable was an elected official who entered their credit card information into a name field when they made a purchase online. It showed up in a banking report and stood out.
The purchase went through because they also put the credit card information into the correct fields.
How did I know it was an elected official?
Their email address had their full name and government department.
Job advertisements are so bad that this delivery job would show up as a "remote job" with some agencies characterising it as "work from home" because it's not in an office.

Just so we're clear, Bluesky is federated just like this place. Twitter was the community square of the planet until Elmo bought it and brought his own kitchen sink because he thought he knew how to run Twitter. That same delusional individual is now advising the elected Orange in charge of the USA.
Whilst Twitter had its problems, they were nothing compared to the cesspool it is today.
Bluesky will no doubt go through growing pains, but I don't see evidence of the same mistakes as you appear to be suggesting.
So, no, I don't think that you're portraying a realistic viewpoint, instead you're fear mongering for no discernible reason, other than to discredit a platform that is evolving and flourishing.

That's precisely what I do.
