Well, the tattoo... it's uhm... it's my cutie mark.
In the dreams, it's the mark that shows everyone what my special gift is... I'm uhm... good with animals, that's my special gift. Even little butterflies love me and don't fly away... this one time, when my dream self was just a little tiny filly, I fell out of the sky, and hundreds of butterflies caught me and helped me descend more slowly so I wouldn't get hurt. It was the most amazing day... and I just knew I wanted to stay down there and be with the butterflies and birds and bunnies and things forever.
