The first stage is born from the idea of voyeurism but centered on me. A metaphor about how to try to understand your own mind, your feelings,
your psyche, is like trying to take a peek through a half-open door, a curtain, or a peeping hole.
And the “boo”? well sometimes what you find scares you, makes you smile, or surprises you.
Hence the name, it’s a contrast between the name of the children’s game and the risks of “peek” as an adult, especially inside yourself.
