Hey Moley,
Have you read this book:
https://www.amazon.co.uk/Sum-Tales-Afterlives-David-Eagleman/dp/1847674275
I found it fascinating. There's so much possibility out there and we have no idea and no way of finding out what comes after and anyone that says they do know is a fraud.
I also found this article very interesting:

It talks about the sensation of "Ego death" when taking DMT, which is somewhat analogous to dying but still being aware. It's all in your head of course, but it perhaps gives an insight into a world without you in it.
