Strange

There are a couple of things that seem odd to me about this film. I'm not the sort who normally picks holes in plots but it really struck me that a number of strange things happened.

First it looked like an obvious set up. The woman gets some poor sap back to her appartment only for her jealous and violent boyfriend to 'unexpectedly' appear and need to be killed. But Wanley never suspects. It doesn't make much sense that she'd invite a complete stranger to her home to look at pictures of herself, it feels like there needs to be some further justification. Later she needs money and he gives it to her unquestioningly even though he has no evidence this guy has turned up to blackmail her. It seems odd he never questions her honesty. I assume this was to throw us off and make us suspect she's playing a bigger game, although it worked on me it means some things don't make sense when she turns out to be ok after all.

After killing CM, Wanley knew he'd have to drive all the way out of the city, yet he propped the body upright in his car and removed the blanket. Why not leave him on the floor covered in the blanket? Anyone glancing in (such as the toll guy) would just see a nondescript bundle on the floor.

Why did the police assume the blackmailing thug was the killer? We learn that the police know of a shady character who was following CM and they even assume he will try and blackmail the killer. So when somebody turns up with the dead mans watch (an indication he was connected to him) and a wedge of cash (an indication he was blackmailing someone) why did they assume he was the killer rather than the blackmailer?

And don't get me started on the convoluted and reality-stretching way they got Wanley out to where he'd dumped the body the previous day!

Anyway, the fundamental question, I suppose, is am I being picky with these issues, or are they (and many others) deliberately stretching plausibility as a result of the whole thing being a dream? Are these 'unrealistic' plot devices meant to be:

1. Clues for the audience that we aren't watching something real.
2. Liberties taken by the filmmakers because it's all a dream so they don't need to worry about believability and can throw in what they want.
3. The usual minor plotholes (and/or audience misinterpretations) that most films feature to one degree or another.

I liked the film very much but was left with this niggling uncertainty.
