Oh god, I have absolutely horrid nightmares about winning the lottery and then having terrible things happen to me or my winning ticket as I am on my way to claim it....
It blows out the car window....
or
I get to the claims station (after telling my boss to kiss my arse) only to find there was a technical glitch in the ball machine and the drawing has to be re-done....
or
I put the winning ticket in a "safe" place, only to find the next morning it just happens to be my 3 year old's "favorite" hiding place as well...
or
the ticket machine that issued my ticket has a slight problem and the lottery commission thinks my ticket is a fake....
or
I get into a car wreck on the way to claim my prize, wake up in the hospital 2 days latter and the ticket is nowhere to be found...
Ugh.......
