It depends on the person. Some people have lucky numbers. If 11 is your lucky number, it might symbolize success. Also, very important things in someone's life often have some number in them (say, your dad dies on the eleventh day of a month, or at eleven o'clock, or in romm number eleven). If this is the case, when you are interpreting the dream, and you see 11, think of the things and emotions that happened in that important event. It is probably those things and emotions that are important in the meaning of the dream, not the number 11 itself.
