This may get a little trippy, but if you loosen your gears a little, you might enjoy the ride.
When you work on the edge of life and death, you're working on the line between here and there. Here (life) is something we know about and are familiar with. There (death)is the world of speculation. In a sense, death is somewhere anything can happen.
Our imaginations can take us anywhere. But they are also where our creations originate. What the mind sees, we can create. Take a walk around and through your rig...uh, I'm sorry, truck. There's not one thing you see that did not originate in someone's imagination. Thoughts are real, and do take physical form; even if we can't see it; take electric current for example.
Everybody has tried to take a crack at defining there. When people get together and agree on what a there looks like, what happens? A bunch more people start seeing the same things! Literally! So the spirits and other manifestations of there that they see are real. They DO happen to someone. As a concept to play with, let's call them thoughtforms, as in the appearance of an image of the Virgin Mary materializing on a refrigerator door.
Most people I know have had an experience or two that could roughly be described as stepping through a crack into some other plane, some other reality, maybe even someone else's reality. Can you honestly say you never have? I'd be interested to hear.
It's my position that when any one of us begin to participate in the life and death struggle, we are exposed to different planes of existence. It could be nothing more than being in the middle of the belief systems of those people who surround a dying person as we work him or her up. Or even the belief system of that very person!
Could you accept that sometimes, doing this work, we get exposed to such forces, and that such forces are real? The idea is, HERE you can help each other find metaphors to describe and make sense of your experiences.
I hope this turns into an exceptionally FUN thread, where without judgment or derision, room can be made to broaden our experience of the work we do. Thank you for bringing this up!
(For clarity's sake, I left the field in 1985, but the things I was exposed to in the back of an ambulance opened my eyes to many different levels of experience. I've been exploring them since, and am happy to share and learn more.)
