That's stage one.
It's very light.
This is also where you get hypnic jerks.
And you, if you have one of those, you were in stage one sleep.
Totally normal, medically harmless.
Everyone gets them.
So that's stage one.
It's a light transitionary stage.
Then you drop into stage two.
Now stage two, when you first drop into it, you're in it pretty quickly.
But for most of the night, that's actually what you spend the most time in.
Stage two is sometimes called light sleep.
I don't like that name for it.
I like just calling it normal sleep.
It's regular sleep.
It's vanilla sleep.
It is more than 50% of the night.
Most of the work that your brain does in sleep is done in stage two.
Um,
But then you drop into stage three, which is also, you know, in our world, we call it slow wave sleep because the brain waves are bigger and slower.
