Odd Numbers – Numerology is very difficult to determine in dreams and it is rare to have a dream of numbers at all, much less something so vague as odd numbers. Different numbers generally mean different things. However, odd numbers are mostly lucky numbers. The numbers 1, 3, 5, 7, 9, and 11 are considered by some to be the most lucky numbers known. The number 13 is generally thought to be unlucky, though by some it is a lucky number. Odd numbers larger than these are generally thought to be lucky when they are prime or a multiple of any of these single digit odd numbers.
