Martin is most likely experiencing night terrors, which is a sleep disorder that appears on children from age three. Night terrors consist on the appearance of an intense feeling of terror while sleeping, normally during the first 3 or 4 hours of sleep.
To help his son with this sleep disorder, Martin's mom should use scheduled awakenings 15 or 30 minutes before the episodes typically occur. Awakening Martin fro a brief moment at night will help him avoid having night terrors.
