As you can imagine, I see a lot of dead in my work, whether I'm just out and about on my own, or when I'm called by clients who are having issues in their home or work space with dead who are stuck and seem unable to move on and are either causing serious issues or just disruptions in the lives of the living.

it seems that when we die there's oftentimes really no one there to tell us what comes next. To help us figure out where we go from here. To point us in the right direction.
I can only see so far after someone crosses. What I KNOW to be true from the years I've done this are:
- First, time doesn't seem to pass in quite the same way once we die as it does when we're alive. I haven't quite figured that one out, yet...
- When someone dies, they don't become wiser. They can't see the past, present, and future. They don't generally change in any real way (other than their form, obviously), so any character traits that were acquired on this side roll over into that side, too. For instance, a racist while living will still be a racist on death until he moves through the processes of dying and transition. In other words, we don't seem to fundamentally CHANGE when we die. We're still the same spirit we were in life. When people first die, they spend a bit of time mourning what THEY lost. After all, just as the living have to deal with the loss of this person in their world, the person who died mourns what he's leaving behind. This can include visiting family members, going to his funeral, and trying to wrap up any loose ends he's left which can also include finding someone like me who can reach out to the living and act as their voice.
- What happens immediately after he dies is also tied to his beliefs about death while he was alive. It would appear that, if we have a strongly-held belief about, say, purgatory, we experience something very like purgatory. If someone believes that nothing happens when we die, they have a very difficult time coming to terms with the fact that they are dead and something is definitely going on as they've not just ceased to exist in any form. Whereas someone who really has no idea of what happens next, but is open to anything that might happen tends to move on to whatever's next with relative ease. After the initial mourning period is over and the person has come to terms with the fact they're no longer physically present in this world, they generally go somewhere where I can't see them. BUT, I can feel them there and know that they're with their loved ones and Guides/angels who are helping them learn the lessons that they needed to learn from this lifetime before moving on to whatever's next.
For people who have no strong belief about what happens after we die, they seem to move through this process and then to whatever's next in a relatively fast way in weeks to months. If they were ready to die when they left, all the faster.
But, I've always found it extremely odd how many dead are 'stuck' here. Seemingly as if no one ever met them when they arrived there, or provided any sort of direction as to what was going to happen next or what was expected of them in order NOT to be stuck.
I've pondered this for years. I'm serious. For YEARS. But a few weeks ago, I had an especially puzzling client/haunting situation and was thinking about this again when talking to my Guides and asked them if this meant that there was no god, stating that it seems fundamentally unfair that we should die and have no direction or help when we cross. But, his answer sorta blew my mind:
"Why is it so puzzling? It's how you're born into THIS life, isn't it? Not knowing anything, having to learn it all by trial and error? With no guidance other than experience?"
Right. Totally right. That's EXACTLY how we come into this world. So, now my question isn't whether or not that's an indication of the existence of a higher power/god, but rather, is death from here rebirth somewhere else?
