Who can I talk to that will help me with my nightmares?

There seems to be something pretty deep going on here, and it seems like you may have post traumatic stress syndrome. Do you have anything in your history, any recollection that you were ever molested as a child, physical beatings or verbal abuse, or anything like that? A rapist in a dream represents someone who has violated you physically or emotionally. The action of the third cat in the dream implies a threat of some sort as well. An unnatural and dread fear of the dark doesn't come from nowhere, and there also seems to be some sort of an abandonment issue going on here. A state of constant panic will interfere in having a normal life, and this dream seems to have brought some very uncomfortable feelings to the surface for you. If you don't have a conscious recollection of abuse in your past, you may have some repressed memories that are trying to make themselves known to you. If you are walking in a constant state of fear and having panic attacks all the time since having this dream, perhaps you should consider talking to a counselor for awhile, and see if you can find out what is at the root of all this. The energy of this dream seems a bit deeper and more traumatic than a question in a q and a forum can handle. Good luck...
