Okay so just about everytime me and my friend get high and go do stuff together we both realize exactly how this is the beginning of some movie and the ideas we concocted in our head are things that would happen in a movie. So my brilliant conclusion; the people who write movies (mainly suspense/horror movies) smoke pot then write whatever they think.
Haha same, i always think to myself "ohhh this would be perfect for a movie!" funny thing is me and my friends are into moviemaking, so maybe one day we will make a masterpiece...
