just thought i would add a few other things to think about,
the way to truth lies between opposites ,this is the middle way,
being told you have an illness that is life threatening must be difficult to accept,and may as a metaphor represent the feeling of having to let go,you have no option,but i think this dream is more about surrendering to life ,this will lead you to yourself,
as tony stated your dream is full of 2's,opposites,the house you arrived at by the ocean,this is the middle place,a place of healing and rejuvination,
the shore representing the material world,the ocean ,the vast unconscious world,the female with the two differant coloured eyes reminded me of someone who walks with one foot in the sea(unconscious) and one foot on the land(material),and she to is a part of yourself,if there is one thing i have learned it is this, you can trust this aspect of yourself,she/it knows the terrain well,and does indeed walk in both worlds.
i think the ref to ,being home,may be about your acceptance of the feminine qualities within yourself or that you need to accept them, by this i mean as tony again suggested,let intuition guide you rather than rational thinking,
interestingly,the 2nd stage in the so called individuation process according to jung ,is a meeting with the feminine ,
hope this is of use to you,
