what happens after death?

"After death you keep repeating your life over and over and over and over. :D"

I actually watched a documentary about the last moments of life that basically says this could be true!
Basically, as you take your last breath, your brain is still active for about 7 minutes and in those 7 minutes you may relive your life in it's entirety o_O!

Or simulation theory is true and we're all just in the matrix. lol
