Prophetic Symbolism of Numbers.
Numbers:

Numbers can be a very complex form of revelation, especially when combinations of numbers emerge within the dream. In the Hebrew scriptures numbers were assigned to each of the letters of the alphabet. This would seem to be an all inclusive standard for interpreting visions, dreams and prophecy. However, I want to advise caution here because Numerology can easily be manipulated to say whatever the student desires. I would generally advise you to look at the context of what God is revealing through words, feelings and pictures rather than numbers. Remember, don't get distracted by the method that God is using. Your desire and focus must be upon discovering Him. Some people get consumed almost to the point of becoming infatuated with the process of communication, instead of getting to know the Lord who is communicating.
Below is a simplified version of what numbers may mean:
1 - unity, God
2 - double blessing or anointing, or two confirmations.
3 - trinity - divine perfection
4 - earth number, 4 seasons, or four directions.
5 - grace
6 - number of man, 666 represents man in league with the world, flesh and devil or an Unholy Trinity.
7 - perfection
8 - resurrection, new beg, # of Jesus
9 - divine # (3 squared), # of Holy Spirit, also judgement, evangelism
10 - world # (10 horns of beast,10 toes on statue)
11 - incomplete, not yet a government, prophetic anointing
12 - governmental perfection/authority
13 - sin #, speaks of rebellion
