The only thing this is a sign of is that you watched a truly dreadful movie.
Seriously, I always worry about "signs" and things that are "bad luck" and stuff like that. But it's all in our heads. None of it is actually real. I could give you a huge list of things I thought meant something terrible - none of them did! Being superstitious is crappy, and often seems to go with HA - I guess it's all a form of OCD? But you don't have to worry about them.
