Random Riddle: For A Short Time

I seem to come out of nowhere at all
Then quickly disappear like the dew fall

Once I get out, I can spread like wildfire
But before too long, my life will expire

Where one resides in the grand scheme of things
Dictates the emotions my telling brings

When I break, my end’s not yet realized
I’ve just begun making people surprised

What am I?
