 CONT: Towards the end of the movie, Nancy was about to go home and  go to sleep so she could bring Freddy back with her. She told her  dad to come break down the door in exactly 20 minutes so he could  get Freddy. In the 20 minutes before she was scheduled to wake up  from her dreams, she was able to string up all those booby traps and  have a heartwarming talk with her mother and then proceed to fall  asleep to go get Freddy. That seems highly impossible.
