I use Love PDF for most things but there’s a few online resources for editing PDFs that are good.

A long shot but Google Scholar may have some pages/chapters?

I have what I call movie dreams, sometimes they are fantasy, sometimes they are more non-fiction. Sometimes I am myself, other times I am a character and there’s even been a few where I am merely the camera -as I’m im not in the dream just observing. One of the fantasy ones that stands out was pirates fairies and elves, but in space. I was a shapeshifing fairy that was tasked with protecting a group of elves from pirates. I was setting decoys and running from and fighting pirates.
