WHY DID HE BEAT?????

THINK OVER THIS!!
A great industrialist has planned to go for a trip abroad by plane.He prepared every thing ,tickets,clothes ,money ,etc....Suddenly the night watchman of his industry came to his house and asked him not to go for the trip ,as the plane crashed and many died ,while in his dream in night ,the day before.
The man canceled his trip ,similar to what the security said ,the plane crashed and many died as well..........
But the man had beaten the security and sent him away from the job!!!!!!
Do know why ?think over it!!!!!!!!!!!!!!

as he said everything came in his dream,the man realized that he had slept the night before without doing his job,since he was the night watch man!!!!!!!
