Sleepwalking is also called somnambulism, from the Greek "Somnus" (sleep mode) + "amb" (to walk). Most of the dreamers remember little or nothing at all about what happened to them at night.

Scientists unanimously claim that sleepwalking has a genetic predisposition, but so far they have not been able to prove it.
