What is fear? Fear is a chemical reaction in the brain that strikes whenever you experience terror. Fear is primal. Fear is baser. Basically, fear is an emotion, and no one is without fear. Fear is what drives us to defend ourselves and our loved ones when needed. Most of all, fear comes from the unknown. The unknown is what we don’t know, or what don’t want to know. Yet all the time, it comes to us in the strangest ways. That’s what ‘I Must Be Dreaming’ is all about: striving to discover the unknown; about three people struggling to uncover the unknown—before their fear gets the best of them.
