Surely it’s the perception of being unable to leave, and the perception of feeling threatened that causes the trauma?
There’s that research about children experiencing bullying and peer group fall outs in the survival areas of the brain- to them, it’s a survival issue even if their rational self understands it is not.
The continuous, ramping up of pressure, moving the goal posts, being in the dance off despite a high score, so feeling as though no one likes you… Then the exhaustion, both mental and physical, until you can’t think straight or organise your emotions.
Your dance goes brilliantly and you think it’s a triumph, then the judges all criticise it.
The moment standing, waiting for the red light to come on you. I can’t even watch it, let alone be subject to it.
From amateur theatre days, being shouted at because I forgot to wear my tights with my dress, or left sweat patches on the arms… The costume department would be tutting if you lost weight faster than expected, and commenting on your stubby legs or strangely shaped bust…
And that’s without mentioning your partner’s standards and your family’s reaction.
Honestly it sounds traumatic to me- I know I could never do it.
