Factual error: The moment Nancy's digital watch hits zero, her bedside clock rings waking her up. You cannot set an old, mechanical style alarm clock to go off with anything like that level of accuracy. (00:32:00 - 00:33:18)
Continuity mistake: After Nancy gets out the bath, the big mirror goes from having slight condensation on it, to being covered in condensation between shots. (00:32:40)
Continuity mistake: When Nancy gets out the bath, and after her mother leaves, she locks the door then leans back on the sink. Between a wideshot and following closeup, as she leans back, the way her towel and bathrobe are positioned (around her neck) changes. Also, into the wideshot she crosses her arms yet it the closeup her left hand is up by her shoulder. (00:32:45)
Continuity mistake: After her mother leaves, Nancy rests in the bathtub, putting a cloth on her face and leaving her left hand by her left ear. In the following shot her left hand is in the middle of the tub. (00:32:55)
Audio problem: Nancy is watching 'The Evil Dead' in order to stay awake, but the audio of the film heard doesn't match with what scene is playing on the TV. (00:33:10)
Revealing mistake: When Nancy gets pulled under in the bathtub, you can plainly see it's the actress' stunt double. (00:33:20)
Continuity mistake: After the bathtub scene, when Nancy opens the mirrored medicine cabinet and removes the bottle of Sta-Awake, her fingernails are short as usual, but in the bottle's closeup Nancy's fingernails are quite long. (00:34:10)
Revealing mistake: When Nancy sees Tina wriggling around in her body band and a centipede comes out of her mouth - you can see this is a doll that the centipede crawls out of. (00:38:35)
Revealing mistake: When Nancy is running up the stairs in her house to escape Freddy for the first time her foot hits the steps and go through the steps into some goop. Look at the steps above that step and you can see the pre-cut holes where the next sets of goop will be. (00:39:10)
Revealing mistake: When Nancy is running upstairs, and struggling in the goop holes, we see a shot of Freddy smash his arm through the small door window. If you play in slow-motion, you can see a large pre-made crack in the window to make it easier for him to smash, which WASN'T there when Nancy ran through... (00:39:15)
Continuity mistake: When Nancy tackles Freddy on her bed, the alarm clock on her bedside table is away from the edge of the desk. Yet in the shot when Freddy and Nancy roll off the side of the bed, the alarm clock on the bedside table has noticeably moved right to the edge so that Nancy can grab it as she falls. (00:40:05)
Continuity mistake: When Glenn is in Nancy's room to wake her up, she awakes from the nightmare, her mother comes to the door and Glenn goes out the window. Nancy shuts the window behind him. After her mother leaves, the window is open. (00:40:50)
Visible crew/equipment: When Rod is being strangled by the sheet in the jail cell, watch as it goes around his neck and you can see the wire in the sheet that pulls it. (00:42:20)
Continuity mistake: In the prison cell, just before Rod falls to the floor because notices the sheet wrapping around his neck, between shots the way the sheet is wrapped around his neck changes. (00:42:45)
Visible crew/equipment: When Nancy and her mother take off with the car after talking to Nancy's father, you can see the camera man, the boom microphone, and the whole film crew reflected in the back of the car. (00:45:25)
Continuity mistake: After Rod's funeral where Nancy's mother is about to get into her car, there's a shot of her saying "I'm going to get her some help". There's a gravestone behind her that reads "Coulter". When we see her entering the car, with her relative position unchanged, the gravestone reads "McRenolds" (00:47:05)
Continuity mistake: After Nancy wakes up from her nightmare in the dream clinic, her mother discovers her arm is scratched. The tape that was on Nancy's chin has gone, but returns in the next shot, only to disappear in the next. (00:48:50)
Revealing mistake: The day after Nancy comes out of her dream with Freddy's hat, she goes into the kitchen and drinks a big cup of coffee. Firstly she chugs a full cup of hot coffee. Ouch...how did she do that? Secondly she does it without swallowing once. Watch her throat. (00:49:40)
Continuity mistake: When Nancy throws her mother's bottle to the floor she throws it bottom first. When it cuts the bottle lands on its side. With the velocity the bottle was thrown it would have landed bottom first. (00:51:40)
Answer: 1. Freddy is the ghost of a child killer, he is very difficult to be rid of. He did not die at the end of this film. 2. It is possible to bring items and even people in and out of the dream world. Although it is never explained in detail how. 3. It was a dream, but as seen in the film, that's not a good thing.
