Seeing that the incident that triggered the dream is unknown, I am now attempting to interpret the dream in a general sense:
A familiar house that was mine: This speaks of a church or congregation or your personal circumstances (personal interactions with people).
Women friends visiting: You were hosting friends. So they were in your house, which makes you the primary person or the person with influence.
Delaying them causing one to be raped by a man: This part is a bit negative. It could speak of you hindering (delaying) these people, in a spiritual sense, causing them to be vulnerable to the wrong doctrine. And yes, it was not your fault that she was raped.
In dreams and visions, rape symbolizes the aggressive, unfair, and cruel attitude and acts of people in persuading other people of their spiritual viewpoints and beliefs. These kinds of people actually attempt to force people to believe and to accept their beliefs. Whenever a certain belief is firmly established in a person then it becomes permanently part of that person, it becomes “seed” in him or her. It becomes part of his DNA.
When such a person rapes another person in a dream he actually forcefully deposits his “seed” into that person which symbolizes him forcing his views on spiritual matters or non-spiritual matters onto such a person. In this case, being viciously raped speaks of a very emotional argument about doctrines, if it is spiritual. This could also symbolize non-spiritual argument. Ask this lady, if she is known to you if such an incident did occur. If not, it may occur in the future.
So the rape was not your fault but the spiritual hindering was. She was not prepared to deal with this person because of that (man or woman – both can rape a person in the spiritual realm).
Fortunately, this incident was not too serious because you could deliver the person. The fluid speaks of a spirit or influence. She was not possessed by this spirit but just influenced in a negative way. So you destroyed the negative or bad influence by counseling the woman and by restoring her emotions (fluid leaving her).
My opinion is that this is all about an emotional argument about doctrines and your counseling the woman restored her emotionally.
