You had literally -zero- input in what your brain gave you as an answer. It just gave you something, you can make up whatever story you want to tell yourself, "it's my favourite movie", "I saw it last week", whatever you want. It doesn't change the fact that the words on your screen triggered some neural pathway in your brain that is totally out of your control and landed on "Titanic".
It's how literally everyone thinks. Your thoughts come unbidden via a process you do not understand and cannot observe and your consciousness follows them along. Your brain is not as special as you imagine.
It's like we have little thinking sub-agents auto-completing cognition tokens in the background that then surface findings to the main agent which then auto-completes some more cognition tokens in the foreground.
