Visible crew/equipment: When Nancy "jumps" from the boiler room to her front garden you can see her land in a pile of bushes. You don't even have to look closely to see the big black air mattress she lands on. It actually bounces above the fake bushes and becomes almost completely visible.
Visible crew/equipment: This is during the part where the girl dies in the bedroom with her boyfriend (where she gets dragged up along the roof). Just before, when you see the marks made by Freddy's glove, and her hands come up to show her pain, she clearly grabs a chunk of the thin latex pad (best viewed in slo-mo).
Visible crew/equipment: When Nancy is in the dream clinic the doctor attempts to give her an injection. As she pushes the doctor away, the bedsheet falls slightly and Freddy's hat can be seen for a couple of seconds. In the next shot, the sheet is above her waist again at which time she reveals that she pulled the hat from her dream.
