Is it normal to suddenly be in a state of exquisite happiness?

I know this is a happiness commonly pursued. But when I was 19 years old I was near the pub and I suddenly went in a state of exquisite happiness. Now I feel, well, normal! And I was hoping to feel happier than that, the years of misery I have, I'm pursuing exquisite happiness. I feel though I was born in Australia I don't belong here, I belong far away in the misty cold, as my pursuit of idyllic happiness, is this normal?
