Have you ever noticed how unpredictable life is and the years we get? exactly!!
I always had this idea somewhere in my mind and then Nolan gave life to it, I always wonder why some people die right at birth and some in the middle age and some still alive in their 90s and why when you die in your sleep you wake up?
Also you don't know it was a dream until you are awake no matter how weird the dream is, you don't know how it started, same way we don't know how the life started we just believe when people say we were born and did this that, but honestly no one knows the 1st few years or we can say the start of the dream we call life, weird right? what if this is an actual dream and the life span is only based on how long did you sleep for.
The movie will make you question your reality and may make you Mal, so be very sure before you watch it, it can ffkk ur brain forever, like it did to mine, been 14 years still not sure if it's reality or a dream,
Jokes apart- Must watch go for it, nothing in history of cinema is made like this, just pay attention, do not skip every single detail in important.
