I don't know specifically who Eli Weaver is in this story as there's not enough information. He could be an ordinary person with an extraordinary experience.
Not really. Eli might not be a typical ghost story. It could have elements that make you wonder, but it might not fit the traditional ghost story mold.
I'm not sure specifically what 'ellis stories' are without more context. It could be personal stories about someone named Ellis, or perhaps it's a collection of fictional tales related to a character or place named Ellis.
There's not enough information given to really define who Eli is in the bearded stories. It might be a unique name given to a character in a local or niche set of tales. Maybe it's a name used by an amateur writer in their collection of bearded - themed stories.
