Did you know that nearly 75% of all 'ghosts' are still alive?
No? Well, they are. They're just silly sods having OOBEs* or they're Remote Viewing. And 99% of those are doing it unconsciously, either while dreaming or daydreaming.
You can imagine how crowded it is already, after all there're far more dead & undead people (and things) than living people (and things). All these extra astral forms dithering around the ether make unlife very frustrating for the other one percent of us.
I mean, hardly anyone indicates to make it clear which reality they're going to emerge into. Changing ether-strings without so much as a by-your-leave is most vexing, too. However, by far the worst culprits are those who run red lights, jamming up the sublayers causing massive spectral backlogs before all suddenly emerging into the same reality at once - More often than not, unwittingly dragging along other genuine ether-users. Invariably, they often emerge in some weak willed thing who has to be exorcised to get rid of all the extra souls scrabbling about for space in its consciousness.

I'm taking a pair of scissors with me next time I go. I'll cut the link between the astral form and its body of whoever gets in my way. They can drift around for eternity learning some bloody manners, I hope.
Actually, there really ought to be some sort of exam or test one has to take before sliding into the ether. You know, something you have to do to get a license...
* Out Of Body Experiences, for those that didn't know. If you don't know what Remote Viewing is, I despair... Oh, all right. Have a look here.
