This is a really intriguing story, @calluna! And thank you for sharing your editing process in the post comment.

My suggestion, if you are open to further edits, is to find a way to indicate who is speaking. You can reduce the dialog somehow to gain additional words, for example, and use them to add description of the person talking in the dialog lines. Or group together dialog and action so that we know the action is by the same person who is speaking.

There are three lines of dialog and two of action. But I am not sure whether the actors are those speaking. So, for example, if the actor in the second paragraph is the speaker in the first paragraph, you want to combine those in one paragraph. Please let me know if that makes sense!

Here's an example of an edit that would give you more words to use for indicating who is speaking:

This line is 10 words: “She only invited you because she felt she had to.”
This line is 3 words: “Please go away.”

The meaning is slightly different, of course, but I'm just using it as an example. With the extra words, you can say who speaks that line. Something like this:

He waved his hand. "Please go away."

By combining the action with the dialog, you show us who is speaking. Then you can make it clear to readers if the man in the cheap suit is the ghost, and if he speaks, and whether the bride speaks or it is someone else altogether who speaks the dialog lines. I hope this helps!
