For us 12th housers Neptune is on our sun, the sun is identity and Neptune rules spirituality, mystics, imagination, compassion, love of the arts, drama or film, and even chemicals ,, Neptune dissolves our ego and Neptune is compassionate and universal,, for you 12th house people never give up and most importantly never hide your light under a basket. Since we have very little boundaries we are more flexible then most and can do more then most people. We have a distinct sensitive and emotional quality and we can heal others !! We are empathic and intuitive healers and have an psychic antennae to the surrounding people and environment. We might receive Information via Dreams and Meditations. We are attracted to anything that will help us transcend and achieve Euphoric states rather that be Meditation, Drugs, Television and or Music. We are open conduits of the spiritual realm and receive and use this very easily. I would suggest meditative music, reading the bible, praying anything that will open yourself to the spiritual realm and anything higher then yourselves. Also maybe a charitable organization or anything humanitarian therefore by doing this we are using the positive aspects of Neptune instead of playing the martyr or being the victim. Many of us who have a 12th house sun had a weak male figure or missing father figure and spent sometime trying to receive this fatherly love. Many of us are very idealistic About men because of this. However other 12th house sun people might have had a Father figure who nurtured our needs emotionally and spirituality or had an Dreamy , Spiritual or Loving Big brother to Direct, teach and lead the way. Some Our childhoods may have been unfortunate or had a lack Of boundaries. Many of our memories of our childhood are removed from reality,, we look back as if it was a movie or flashback. This can be caused by certain music, movies or even pictures and can bring back many emotions such as pain, depression, unforgiveness sometimes even a feeling of Claustrophobia and or even euphoria wishing to go back( if it was good ). Because neptune (the 12th house) is clouding our sun ( our identity ) many of us have a air of mystery or even mysterious persona, we are hard to pin down. A sun in the 12th house is almost identical to a sun conjunct Neptune or sun in Pisces
