My perspective on beliefs about the afterlife is this: if there is anything we should have learned from the Witness experience it is that the more conviction we have in a belief (no matter what it may be) the more difficult it is for us to learn, grow, and experience consenual reality. I think there is a lot positive to be said about an individual who is open to examining new ideas and information without being judgemental of someone else's progress in their understanding of how things fit together. I know this is hard to do if we really believe something, but we would be smart to be skeptical and open about our own beliefs.
I can say this about my own beliefs is that they evolve and change. I tend to be a pretty hard core skeptical and scientifically oriented person. I want to see evidence for any theory or hypothesis, and the more radical the new idea is, the more supportive information I need to feel comfortable with accepting the new concept.
How all this relates to the afterlife goes like this...right now the scientific community, in several fields, (like physics, cosmology, astronomy) are going through a remarkable period where a lot of established beliefs are crumbling. While there is no wholesale exodus to New Age thinking, I would feel safe in saying that our understanding of reality in the past has been fundamentally flawed and many new discoveries are being made that suggests that maybe it isn't so crazy to believe that our material universe is all there is. Many cosmologists now subscribe to the multiverse theory which says that our universe, everything produced by the Big Bang, is only a small grain of sand in a seashore of other universes. Physics is showing us that mathematical models are showing that even our familiar 5 dimensions are an illusion and that what we experience and see is only part of reality. Astronomy is showing us things we just cannot explain in our current worldviews of how things work. Other scientists are showing things once considered impossible (like the positions of the planets effecting our lives) are in fact happening and scientists brave enough to investigate several well known mediums who supposedly contact the dead, have found out that they cannot explain away the incredible odds that something very strange is happening, and that information from the "other side" is coming through that defies the laws of chance.
All this is disturbing to rationalists who want a nice and predicatable model of reality. Most people don't enjoy uncertainty and the end result is that a lot of people just dismiss anything "messy" like this. While we should be skeptical, we should also be open enough to investigate things that just don't fit in our current beliefs instead of making a blanket dismisal of anything that doesn't fit. Besides that, you would be missing out on all the fun. My suggestion therefore is to keep looking, develop your truth telling tools and skills, and see where your investigation leads you.
Kind Regards,
