Ok. This one is full of nonsenses.
1. A woman is a sleep doctor. She's working day and night. Wait...when does she sleep ?
2. They study people in special bedrooms, and said "there are cameras inside". Wait...no mic ? No motion detector ?
3. It's legit to have all doctors to leave the screens survey, both.
4. Looks like they have a few patients to study. However, they are only two : a man and a woman. Go to 5.
5. As they can have to study men too, they don't think to have a few strong male nurses. In case of a father becoming fierce during his sleep.
6. A janitor is always standing behind the door in case of emergency.
7. Yup, a janitor can save the day if you are a stupid doctor.
8. A disturbed old man has the key of the riddle.
9. The ending twist may leave you dubitative.
10. Watch this if you wanna to fall asleep fast.
"A nightmare on Elm Street" and "Darkness falls" are way more better than Dumber.
