Terry Vigus, from Loughton, Essex saw five of the six numbers on a ticket while he was sleeping but woke up before he saw the final one.
But after putting on the numbers 3, 5, 8, 10, 16 and 17 - based on family birthdays - just three weeks later, they came up for real and the 58-year-old and his wife Linda, 58, won a staggering £1.17 million!
Terry told The Sun: "We joked about the dream and said imagine if we won. We can't believe it."
The pair are now going to buy their council house.
Talk about dreaming big!
