In Dreams: The concluding image of Flowering Judas and what it signifies

Flowering Judas, title story in Katherine Anne Porter's first collection, tells of a woman, quite likely modeled on KAP herself?, living in Mexico, from North America - possibly Arizona, where she says she learned to ride - quite good looking, and in Mexico out of a commitment to service, working with some of the leftist political groups (this seems to be during the time of the Pancho Villa and the rebellion?), teaching children in a small rural school, carrying messages and provisions to politically imprisoned - but her devotion to this work, which she can never quite explain or articulate, is hindered by the gallant and intrusive attention of a # of men, in particular the corrupt and unfaithful and cynical head of one of the groups she works with, who comes to her house every night and sings to her - and she's too polite or intimidated by his power to tell him to get lost. His singing, hilariously, is terrible as is his tuneless guitar-playing - a funny send-up of the Mexican troubadour stereotype. The story feels a little aimless and then gets quite serious and pointed in the last page or two, as the woman recollects a man, Eugenio, who has just died in prison - we know little else about him - and, freeing herself from the troubadours attentions she falls asleep and KAP brings us right into one of her dreams. I don't love stories that rely on dreams, esp for the conclusion, but this works very well in the context - her only freedom of thought, it seems, in dreams. She imagines Eugenio leading her somewhere and essentially transforming into a Judas tree, in flower, and she begins to eat the blossoms, and he protests that she is a killer and cannibal eating his body. The religious implications are perhaps too obvious - also, I looked up the Judas tree, which I'd never hear of, and it seems to be like a dogwood with red (blood-like) blossoms -but it's not only the Christ-like death of the prisoner and her animalistic devotion but also the tree itself is an emblem of betrayal and denials (Judas) that she is struggling to devour and overcome - her own denial, her own betrayal of principles and ideals.
