OK but I saw this post on my dash again: http://lal-nila-syrin.tumblr.com/post/119588938491/jumpingjacktrash-coolthingoftheday-trees (on mobile, sorry) and I thought:
What if there are ghosts like that? Like, ghosts that for whatever reason had difficulty absorbing ectoplasm into their body so they had to leech off other things that could do it fine? They’d attach themselves to other ghosts, except that’s so difficult bc they’d just be blasted or knocked off so instead they attach themselves to ghost animals or to trees and plants,
So no ghost likes going into a dense nature area in the Zone, because they know there’s a lot of these types of ghosts around.
I dunno it was just a thought that suddenly came to me, it’s too early in the morning for me to properly think most of this out.
