By the way, any person who was lucky and got a big win when he bought a lottery ticket or just started playing did not think that he would be so lucky. 
And therefore, even for some time after he found out about the win, he is in a state of euphoria or, as you can say, "taken aback" or "fucked up". 
And for some time his head does not understand and he himself becomes like a five-year-old child. 
It is very interesting to observe such a reaction of this lucky man.
