SOMNAMBULE

"She was known to be a somnambule, often sleepwalking through the house at night."

"The somnambule wandered aimlessly down the street, completely unaware of her surroundings."

"He acted like a somnambule when he got out of bed, stumbling around in a half-asleep state."

"The doctor diagnosed him as a somnambule and advised taking precautions to prevent accidents during his sleepwalking episodes."

"The somnambule was found outside in her pajamas, having walked several blocks from her house during the night."
