Mercury in 12th House
A person with Mercury in 12th House has the following characteristics:
He/She has strong psychic sensitivity, which affects his/her intellect and gives him/her intuitive understanding and deep insight.
Alternatively, with that feeling, he/she may become obsessed with paranoid thinking and may cause anxiety and confusion.
In any case, there is a tendency that those gut feelings are more likely to take precedence as a basis for judgment than logical thinking.
He/She is likely to have an inferior complex concerning intellectual ability and feels that he/she is not good at talking and learning and that it is difficult to convey his/her true intention with other people.
With that, he/she easily feels a sense of disappointment to him/herself and alienation that he/she cannot interact with the surrounding people, and he/she is prone to masochistic and introspective thoughts.
He/She is sensitive to the influence of people around him/her and is easily distracted, so to exercise his/her intellect in work, study or reading, he/she will avoid the influence of others and need a quiet and peaceful space isolated from worldly.
