About 幽鬼網羅 and 死者回想録大成

After a lot of googling, I found a Japanese guide which details how to get these.

Whenever you acquire a "death agony thought" from an enemy, you fill one of its three messages in the memoir (bestiary). What this equates to is a lot of replaying stages to roll the dice for Siren (red) enemies, which drop these thoughts. Bosses will drop them 100% of the time, but make sure you have at least one available "death agony thought" slot available, or you won't acquire it and will have to replay the stage. Likewise, also make sure to have slots available while thought-farming, as you can only carry up to 10 at a time. Unlike bosses, you can exit the stage at any time after gaining thoughts from Siren enemies, at least while replaying a stage. (since replaying adds an exit mirror where you start each floor)

I hope this helps someone out there. If you're having issues hitting ctrl+f on the page I linked, try right-clicking and then "view page source," that helped me find what I was looking for.
