Meaning in Dreams

I believe that dreams have meanings that can be different or similar . I had a dream the other night that i was walking to the corner store and there was a little standing on the corner 10 years old crying to another teenage girl to help her cross the street. the little girl continue to cry until the teenage girl said " you are old enough to cross the street by yourself, I'm not always going to be here all the time to help you cross the street ". While i was sleeping, i didn't think nothing about what the teenage girl said because i was dreaming and i though it was nothing to think strongly about. Until i woke up that morning and i talked to my aunt on the phone about some textbooks i needed and she told me that she couldn't buy my books and i had to buy them on my own because she was going out of town and she didn't have the time to order them. Then, as i hung up the phone with her, i thought my dream i had that night about the little crossing the street and said "I am that little girl who always needs someone to do things for her and i am old enough to handle situations on my own now.
