I think something like the Matrix is possible. I took an extra philosophy class back in 2009 and my professor use the matrix as a guide to our course. After finishing that class I started to wonder more and thought about crazy ideas. Some of the things that I wonder or think about I would be too embarrassed to share because people will laugh or think I am crazy. Researching what Stephen Hawking has to say is interested and make you think of even crazier thought.
I have never seen Inception. I will probably will have to look that movie up to see what it is all about. With American movies I will only watch something that has a hidden message. For example, fight club, Matrix, Hunger Game, and a few other.
You should definitely check out Inception, it's definitely thought-provoking in the same level as the Matrix. Once in a while, I do question our existence. How life originated is still a mystery, even after knowing that the big bang created our current universe and we are the result of 2 billion years worth of evolution.
No, you aren't crazy!
