This girl who had the face of an elephant may represent a part of you when you were 14. A face can be seen as a way how a person presents or wants to present themself to other people. From what I could find about elephants, it seems to be a lot related to positive things, being strong and faithful, patient, a solid foundation for succes, holding an honorable and worthy position. So it may has something to do with memories where you presented or tried to present yourself this way, thinking this would help you while it didn't result into certain people treating you in a better way.
