Sanjog Iyer (Heroes)

Sanjog Iyer is a character from the Heroes franchise. He is a mysterious Indian boy who appears in other people's dreams.

Powers
Dream Manipulation: Sanjog has the ability of dream manipulation. He caused Mohinder to relive a scene from his past, to witness two scenes at which neither Mohinder nor Sanjog were present, and to interact with Sanjog via a soccer ball encounter. It is not clear which individual is ultimately in control of the progress of the dream.

According to Chandra Suresh's file on the boy, his ability is to "enter yours dreams, alter your perceptions - a kind of spirit guide". This fits with Sanjog's description of his powers: he claims he does not actively seek out those whose dreams he alters - instead, those with questions needing to be answered come to him.
