Wanted: the Girl with Purple Nails

I had a dream that I was in a very large hall with many others. We were all abducted by women, and the atmosphere was of a school and stern cruel teachers.

I don’t know what was different about me, but throughout the dream I was hiding my identity from the teachers, specially the headmistress. We were divided in groups and stayed in enclosures. It was time for us to go to sleep.
The adults, the headmistress were all looking for me. Every time one of them reached the place I was in, I made sure they wouldn’t see my face. Until one time, as one of them came close, I realised that not all of them can recognise me. I felt a little stupid and relaxed a little. However soon after, I realised that they would recognise my obvious shiny purple nail polish (which I currently have).
The headmistress came and was looking in the place I was at as I started to chip the polish off.
There were two girls or at least one who slept on the opposite side of me, and she was worried because I was worried about getting caught.

Later, we were all are leaving the premisses on a ‘field trip’. I was blending in the lines and minding not to get noticed. When we were outside, in a desolate old village, I ceased a moment and escaped. Climbing onto rooftops and jumping off ledges, until suddenly I froze, out of fear of doing it again and falling.
I was lightly aware it was a dream, so myself told me to keep jumping. She reminded me that I wasn’t afraid before and that is why I never fell. And then she just pushed me onwards, and without thinking about it I jumped to the next roof and felt exhilarated. It was fun not to think and not fear and to be free. I was gliding and short term flying, until I reached the city and the people. I landed, wanting for my feats to be noticed by the dark, bold tall man that I might have bumped to on purpose.
