I would carry my darling back to my father's house in Applethwaite; where, if we lived humbly, we lived at peace. I said I had been frightened enough with the old lord's organ-playing; but now that I had seen for myself this little moaning child, all decked out as no child in the neighbourhood could be, beating and battering to get in, yet always without any sound or noise--with the dark wound on its right shoulder; and that Miss Rosamond had known it again for the phantom that had nearly lured her to death (which Dorothy knew was true); I would stand it no longer.
The above short story is written in 1852. (The Old Nurse's Story by E. Gaskell)
In dictionary, 'deck out' means 'put on special clothes to appear particularly appealing and attractive' means, which is completely out of question in the above sentence.
Then, what is the real meaning in the above sentence?
Many thanks in advance.
