Here's 3 short extracts from my dream dictionary it's entirely up to you if you believe they apply to you,
You mentioned that you were doing your hair in the mirror (the same as my dream)
HAIR:
To be combing the hair is to be attempting to untangle a particular attitude we may have.
MIRROR:
The mirror suggests self-realisation backed up by wisdom
TRANSFORMATIONS:
Dreams where changes occur suggest a shift in awareness & freedom of thought. Once the dreamer understands the change is for the better he/she is able to accomplish changes in his/her own life.
