Something that's always confused me the many times I've seen this great movie: what's up with the scene where Scottie follows Madeleine into the McKittrick Hotel near the beginning? He sees her park her car by the hotel, and then he sees her opening the window in one of the upstairs rooms (this shot is nicely mirrored in the later scene where he first sees Judy, as she opens the window and leans out of her room in the Empire Hotel). But then when he goes inside, she's not there, the front desk lady insists that she hasn't seen her, and her car isn't there anymore when he looks outside the window. So what happened? This is before his nervous breakdown, so things are pretty much by the book in this early part of the movie, and yet this false image/supernatural thing seems to be happening.
