I’ve been researching near death experiences for a while. You could look into that for starters. Also I follow all sorts of hospice nurses that talk about death and the process of dying. It’s a fascinating topic to me as well and I would like to understand.
@Wiseacre No, they're not. We've never heard from anyone who died and stayed dead. It's impossible to tell if NDEs are memories that form before or after unconsciousness. It wouldn't be ethical to put someone in a fMRI machine and induce a NDE, but it would be interesting.
I have a connection to the dead because I've experienced SO much loss. Now I feel most at peace in darkness, silence and graveyards. I spent a lot of time thinking on it and I experience something when ghosties want me too. I have no control over it though.
Research asubha meditation, and go in search of a animal corpse in the forrest etc, and visit it as often as you can and meditate on its progress of decay, as you will not find a human corpse to practise this meditation with. I was shocked when the buddhist nun mentioned this tradition of buddhism, but it was ascribed to help practioners grasp the important law of impermanence.
Instead perhaps you could visit a cemetery and contemplate death and its meanings there, reflect on your own mortality etc.
We are born into this world knowing that we are mortal. We also know that we could die at any time, we see death. How much more connected could we be to death? We have no choice but to accept our fate.
