Some dangers come from outside the house.In Dennis Jarrett's life, danger walked down the hallway.Sleepwalking wasn't a funny childhood phase in Dennis's family. It was an inheritance.As a boy, Dennis watched his father wander the house between asleep and awake-sometimes mumbling, sometimes searching for threats only he could see, and once unlocking a gun cabinet in the middle of the night to hunt an "animal" in his son's room. Years later, Dennis became a sleepwalker himself.From leaping out of camper bunks and climbing invisible trees to patrolling hallways like he was still overseas, Dennis's nights turned into unpredictable terrain. The most terrifying moment came as an adult when he woke mid-episode with a loaded .357 pointed at someone he loved. That was the night he realized he wasn't just a protector. In his sleep, he could become the danger.In Marked by the Night, Dennis Jarrett blends suspense, dark humor, and heartfelt honesty to tell the story of a family marked by sleepwalking across two generations. Along the way, he wrestles with questions that will resonate with anyone affected by sleep disorders: - Is this inherited-or triggered by stress and exhaustion?- Why do some people sleepwalk while others don't?- How do families live with something that's frightening and sometimes funny at the same time?- And why did it all suddenly stop after a lifetime of chaos?Both gripping and deeply human, this memoir is about more than sleepwalking. It's about the unsung heroes who stay awake, the thin line between safety and danger, and the grace that sometimes arrives quietly when the night finally lets go.If you or someone you love sleepwalks-or if you've ever felt like you were fighting battles no one else could see-this story will help you feel less alone, give you a reason to laugh, and remind you there is real hope for quieter nights.
