My hamster is sleeping while standing

[ShadowNinjaHamster]

Hello,
I changed all of the bedding and everything today and so it created a nest and it has it's own little house, but for whatever reason now my hamster fell asleep while standing.
I got him two weeks ago and he has never behaved like that. He's sleeping weirdly. He's like sitting and sleeping and this is not a normal behaviour. Sometimes he also squeaks a little. What's wrong with my hamster?





At the end of the video he's also making weird movements, which I have never seen in two weeks.

Edit: I googled and some sites say it's normal and some say it's not normal. Which one is it? Everything with hamsters is: "It's normal", "Nooo, this is not normal, it's a myth".

I am worried about my hamster. Please tell me if it's normal? Is it too early to worry? He's clearly uncomfortable. How can I make him feel better?

Edit: He changed his position
