I’m in a similar situation. My DH died unexpectedly in traumatic circumstances in January 2025. I spend most of my idle moments (amounting to many hours a day) thinking about him and yearning, pining, to catch him up when it’s my turn.
Consciousness is a big subject and I’m not really intelligent enough to follow the sub-atomic facts of it. But it seems no one truly has a very solid, firm understanding of what consciousness is: where is it located in the body or brain? What powers it? What happens to it after death? Could it - or a vestige of it - just possibly endure in some form when the body is finished ? I hope so. So there’s that, which I think of a lot.
Then there are ghosts. I had a vivid experience of one, just once, but it was unmistakably a ghost. (This pre-dated by decades my husband’s passing.). It had a profound effect on me. It gave me the belief (I prefer ‘understanding’ to belief) that sometimes, something goes wrong with the shut-down, end-of-life process and some ‘souls’ (for want of a better or different word) get stuck. This raises the issue of what happens to those ‘souls’ who don’t get stuck and become ghosts. Are they as active and real (as my ghost most certainly was) in another dimension? It’s possible. There is a lot on ghosts and consciousness that science hasn’t adequately explained.
At this point, it’s also worth mentioning that we are not supposed to know if we can merge or communicate with our dead loved ones, for good and obvious biological reason: if we knew we’d be reunited, many people would not wait out the rest of their natural lives. I certainly wouldn’t. I’d be long gone. So I think biology, evolution, maybe even physics (who knows?) have seen to it that we don’t have the answers.
I'm sorry for your loss, @Magicpaintbrush. Truly, there is no pain like the pain of bereavement.
(Bear in mind, the world is more mysterious than we imagine.). Sending a hug xxx
