Hi Nike, I think it's just a fantasy that makes some feel better about dying and loved ones that have died.
Scared that there is actually an end to life and everything when we die.
I agree with Mikey on this.
Our sense of self is created within our minds.
It is dependent on the physical process of neurons.
When the brain dies, our sense of self ends.
Since our sense of self is completely dependent on our unique physio-electric and chemical make up, there will never be another you or another of anyone else that has died.
While we might find associations with mannerisms of others that resemble someone that has died, it will never be them, or you.
My sister believes when she dies, she will get to see all those she loved.
If it gives her peace, I have no problem with that but I do not believe the same.
If everlasting souls gives you peace, I too have no problem with that.
