I read, and slowly re-read the famous poem “The Raven”, and I figured out that the narrator is himself a ghost for most, if not all the poem, and when he speaks, he is often speaking to (or about) himself (or more specifically, his no-longer mortal “soul”), not the raven or the “Seraphim” (as in, he calls himself a “wretch”, not the Seraphim).
The whole poem explains what it’s like to be a ghost, and what causes it, and the possible direction leading out of it (which he misses out on, namely forgetting Lenore and moving on).
Best teaching on the Ghost Realm I’ve seen in a long, long time!
