In the original sentence the speaker is desolated after seeing the ghost of a beloved one, most likely, his mother. The expression he used 'held her off' means that he did not speak to her simply because he was waiting to feel the presence of a different ghost: Theresias'.
The word see in both the question and the answer can be compared with one another, as well as ''didnt speak with her'' and ''held her off''. Both stating that despite seeing the ghost it had been ignored.
