Do you make dumb mistakes and need more sleep?

[Legend]

I just replied to a thread I made

Sometimes I think of a random general thread, but I search for it first and find I already made one years ago.

I just remembered.  

I once got Star Citizen and Elite Dangerous mixed up.  

I overestimate how much I know about some things, but that's not a sleep issue.

I'm struggling to think of example but I definitely do this.

I don't know if you'd call it dumb mistakes but I often struggle to solve physics/ maths problems when I'm tired. Even ones that I could easily have done a couple of years ago.

Oh this reminds me.
Sometimes on tests, I'll get the test back and I'll be confused why I didn't know how to do one of them.  This is really easy, why didn't I know this?

It happens quite a lot, especially under pressure. Its annoying, but it happens to most people.
