Hi Flash, perception and reality are two different things; the way humans interpret reality is through sensory organs and celular electrical inputs. According to many scientific journals our brains contain a substance called DMT, DMT's effects are strikingly similar to the sensations reported during NDEs, such as a feeling of transcendence, encounters with otherworldly beings, or a life review.
I'm sure that life after death is another state of perception but NOT of physical reality. Also, recent studies suggest that the organic gas released by our bodies after death contains genetic memory which quickly travels along our star's gravitational frequency.
Let's review what the religious scripture has to offer regarding this topic, the Bible takes us through an 12.000 year epic of battle between God and humans and culminates with the transfiguration of the Messiah.
The human condition is perhaps another quantum, gravitational, chemical and gaseous process happening at a micro interplanetary level, the DNA helix contains strategic genetic markers for evolution in the cosmos (Carbon, Hydrogen, Water and Acids). It seems we are stuck to the macro cosmos and not our own perception of time and space.
