I say this with my full chest — Undertone was not lying when it said that it is "the scariest movie you'll ever hear." And I cannot un-hear it!

In this spoiler-free episode, I explore Undertone (2025) and the psychology of sound.

I talk about:

  • How sound can help us form secure attachments 
  • The psychology behind "therapist voice"
  • How sound helps regulate our nervous systems
  • Why we are naturally drawn to live music as a primal act
  • How silence can help grow your brain
  • How the 8 of wands tarot card helps us explore our relationship to silence and the unknown 

Mental Health is Horrifying is hosted by Candis Green, Registered Psychotherapist and owner of Many Moons Therapy.
