Sanctum

What if that voice inside is right all along? Does it sound crazy to assume that more than one person can occupy the same body?

Meet Zorell. Since the age of 12, he has been hearing a voice inside his head. Assuming it to be just the voice of motivation/guidance, he didn't make much if it, thinking it was something normal that everyone has.

Now near his mid-20s, he realises that the voice that has always been his guiding light could, in fact, be a fractured self, waiting for him.

But the big question: Why?
