Given the amount of out of body experiences people have this doesn't surprise me at all. Your consciousness can actually separate itself from your body y'all, not just chill inside your brain for a bit after you die.
Most will say you're talking nonsense, but odds are you're right. Given time this will be proven to some degree in my opinion. Right now it's conceptually absurd to those who have never experienced anything of the sort, and most metaphysical concepts, in general, are HIGHLY looked down upon by a great number of people, especially those who have this crazy rigid view of science itself.
They think even entertaining the notion of metaphysical concepts is for the "stupid", yet some our greatest mind in history explored these areas, and many could argue that some of sciences most fundamental understandings came from people influenced in varying degrees by ideas that would be considered metaphysical, etc.
Curiosity and openness, especially to that which was considered absurd at the time has been proven time and again as a major pathway to some of the most powerful and life-changing discoveries man has ever made and will continue to make (directly or indirectly).
Its much easier to say something is not true, too difficult, is stupid, etc. than it is to think deeply and ask questions into how something could possibly be true if true. This is pretty much how the impossible becomes possible in any field of study.
