From what I understand, heaven is probably the wrong term to use, the afterlife experience will vary, depending on one,s viewpoint, for instance, those who expect grassy flower filled meadows, will get just that, whilst others who expect non stop feasting and drinking will also get what they want, the point is that the afterlife models itself on what the individual expects.But the crux of the matter, is these are just illusions to ease you into the environment of post death existence,to make you feel at home, as it were.
