At midnight, I found my roommate somnambulizing through the kitchen, carefully making a sandwich as if nothing were wrong.

The somnambulous patient wandered through the hospital corridors at night, murmuring fragments of forgotten dreams.

He walked somnambulically through the darkened house, pausing at each door as if searching for something he could not remember.

Her sudden somnambulency frightened the family as she wandered downstairs in her nightgown.

Her somnambulancy worried the family, as she sometimes wandered into the garden at night.

Despite repeated warnings, his somnambulence led him to wander into the garden at night, tripping over hoses and scaring the cat.
