are we even real what is breathing how do we exist why are we here does anything actually matter are we all alone is this a simulation or are we all dead maybe I'm just dead and I'm a ghost and no one has the heart to actually tell me or maybe I'm the only one alive and I don't even know it is this afterlife do we live in multiple dimensions and its all a test and we pass the test and move on to the next stage of being but does anyone know how can we be sure of anything when we are told what to think from the moment we enter this world
