List of movies that can make you reconsider your reality

I fancy watching mind-twisting movies. Many of them have changed the way I see this world. If you are a complicated mind like myself, perhaps you'll enjoy them as much as I do. So here is my favorite list so far:

1. Inception (2010)
2. Interstellar (2014)
3. The Matrix (1999)
4. V for Vendetta (2006)
5. Vanilla Sky (2001)
6. The Source Code (2011)
7. Lucy (2014)
8. Primer (2004)
9. The Thirteenth Floor (1999)
10. The Truman Show (1998)
11. Mr Nobody (2009)
12. Minority Report (2002)
13. The Prestige (2006)
14. Limitless (2011)
15. Revolver (2005)
16. Groundhog Day (1993)
17. Edge of Tomorrow (2014)
18. Shutter Island (2010)

I would update this list as time goes by. Perhaps I forgot some movies I've watched or I might just watch some more in the future.
