Is it normal to easily wake up, but then not be able to get up?

When I'm asleep, I awake to the quietest noise, but then, whilst I'm awake, I can't get up. I can't even move.
Ima add a paragraph to make you guys read on.
Anyway, I wake up and try to lift my arm, but I can't.
I can still breathe and blink, just not anything else.
This can last up to about 5 minutes, and it used to be scary, now I'm just curious... Help?
