This sounds very funny but it's just normal among gamblers especially those that stake to win huge amounts of money and the most funny people that does this kind of imaginary winning are those that plays running bets, there is a stage that the bet will approach and they will begin to look at the options giving to the remaining events then they run into conclusions that they will win the bet after the last event must have played but before they know it the bet will be lost.

Having an imaginary winning in your mind as a gambler is very bad because if you don't win the bet it can cause emotional damages due to the fact that you've already mapped out what to do with the money if the bet wins. This is why gambling should not be taking seriously or as a means to take care of your livelihood because it can disappoint you at a time when you needed to win so dearly in order for you to take care of your bills.
