What effect were the veil and Mr. Hooper said to have had on the corpse at the funeral?

When Mr. Hooper arrives at the funeral, for once, the veil was "an appropriate emblem."  The veil itself and Mr. Hooper's presence seem to match the solemn and somber mood of the funeral, and his mournful aspect enriches the sadness of an already sad occasion: the death of a young maiden.

Then, he bends over the coffin to offer one last farewell to his young parishioner, and "the veil hung straight down from his forehead, so that, if her eyelids had not been closed forever, the dead maiden might have seen his face."  He snatched the veil back so quickly that it caught the attention of the mourners.

One old woman who was particularly superstitious reported that just at the moment when the dead girl would have been able to see Mr. Hooper's face behind his veil, "the corpse had slightly shuddered, rustling the shroud and muslin cap, though the countenance retained the composure of death."  She believes that she saw the corpse tremble a bit even though the young girl's face never changed.
