Numbers can represent material possessions. They can also be linked to financial hopes or concerns. Numbers also carry personal significance for the dreamer. When numbers appear in a dream, think about their significance in your life (a date, address, phone number, etc). Also check your calendar to see if there is any significance to the passage of time (i.e. if 3 was in a dream, look at 3 days, weeks, months, years ago etc to see if there is any significant event there). Finally, numbers carry their own distinct universal symbolism (numerology is the study of numbers and their significance)- see below for some common symbols.
