I am especially interested in ones that you consider tricky or baneful.
I’ve been writing fiction for a long time, but this never happened to me. I guess because my public has always been TOO smal, to the point is really insignificant.
If any thoughtform wants my writing to manifest, I first have to learn one thing: is this an interesting character or no? That would be the only thing that matters.
This mainly happens if there is intent behind the writing, even if only subconsciously. Taylor Ellwood talks about using writing to mnaifest in his book Space/Time Magick.
I don’t believe there are any thoughtforms behind it though, only the consciousness of the author.
