3-5-7is a mindfulness breathing technique; breathe in for 3 seconds, hold for 5 seconds, out for 7 seconds. It is supposed to help you become more mindful as it requires 15 seconds of focus to do one cycle. It's possible that this is about becoming. Not just being mindful, but becoming. Maybe a touch of psychokinesis.

Just a thought.
