You're reading too much into things. Death is no illusion. Death is real. When you die, you cease to exist. It's no illusion that you cease to exist, no, you just die. Is it a point on the map? Yes. Yes, it is. It is our destination, however grim that may seem. And there is no escape either. We can try to seek refuge in religion, or hazy theories like you presented, but in either case, one day, we're going to die and that's final.
