Initially hoping to use his powers to help others, such as warning a woman that her kitchen is on fire, Johnny eventually denies their existence and is relieved when a tabloid reporter, which he refused to co-operate with, decides to label him a fraud. Johnny refers to this obstructed information as existing in the damaged part of his brain, "the dead zone." His visions have limitations and parts of them are often clouded. When Johnny touches certain people or objects, he now sometimes experiences psychic visions relating to them, revealing either hidden truths about their past, dangers in their future, or situations happening in the present that are connected to them. As if to compensate for the damage, a long-dormant part of his brain has become active. Medical testing reveals a minor part of his brain suffered permanent damage. On May 17, 1975, Johnny regains consciousness.

Desperate for hope, his mother Vera becomes intensely religious, believing prayer will bring her son back.

His injuries leave him in a coma for four and a half years. After a date with his girlfriend Sarah at a county fair, he is involved in a car crash. As an adult in 1971, Johnny Smith is an English teacher living in Cleaves Mills, nearby the fictional town of Castle Rock in Maine. In 1953, Johnny Smith is six years old when he suffers a head injury and immediately has a psychic vision of the near future, an event he barely even remembers as an adult. In the TV series starring Hall, the "dead zone" is not his brain damage but instead the previously dormant part of Johnny's brain that awakens and activates his psychic abilities. In the movie adaptation starring Walken, a "dead zone" is a blind spot that only appears in precognitive visions, representing that the future can be altered.

In the novel, the "dead zone" is the part of Johnny Smith's brain that is damaged beyond repair, causing dormant parts to awaken in order to compensate, leading to psychic abilities when information in his visions is obstructed, Johnny says it exists in the dead zone.

He possesses psychic abilities that allow him to see moments of the future and past, usually triggered by touching objects or a person related to that future.
