Question

Sleepwalking
Read the text and answer the questions
Lizzie heard her alarm and woke up. She was disoriented; she was on the couch but the sound of her alarm came from her room upstairs. Had she fallen asleep on the couch? No, she distinctly remembered getting in her bed. She must have been sleepwalking.

She was a little worried, so she looked up sleepwalking on the Internet. She found that sleepwalking is considered a parasomnia, an unwanted or undesirable behavior during sleep. Well, she certainly found it undesirable! What if she had done something dangerous while sleepwalking?

Sleepwalking occurs during the deepest stage of NREM (non-rapid eye movement) sleep and most often occurs in children. It can be caused by sleep deprivation, stress, or fever. Lizzie had stayed up late studying, so she figured stress and fatigue both contributed.

Sleepwalking is fairly common, Lizzie read. About 18% of the population does it at some point in their lives. It’s not usually a cause for concern, but the sleepwalker can possibly get hurt or embarrassed by an episode. Lizzie decided she would not stay up late studying again!
