In a horror film when the teenage girl says ; "Theres no way the killers in this house", we already can logically guess that the killer will be in the house. It is the directors attempt at dramatic iorny and is part of the horror cliche we grow used to from thousands of low budget slashers.
But thats it.
If we saw a movie togethor and I say; 'I bet the Daleks lose', and you think they're going to win, and then they DO win, then that was going to happen all along, and has nothing to do with your thoughts. The plot of the movie will not change in order to remain consistent with your mind.
