Sleepwalking is more common than previously estimated, according to a recent study in the journal Neurology.

The survey, conducted by the Stanford University Sleep Epidemiology Research Center, involved 19,136 Americans ages 18 and older from 15 states, finding that 29.2 percent reported a sleepwalking episode at some point in their lives. That included episodes in childhood and adolescence.
