It could represent a greater level of awareness where by the your conscious and subconscious elements are becoming more familiar and are embracing one another.

To put some distance between them and yourself.

Do you feel that you current living arrangements need a change?
Are you being forced into doing something you don't want to do?
Do you feel as though you are giving up something, or part of yourself, to make someone else happy?
Have you been feeling angry or stressed with someone, or a situation?
Are you feeling your body's biological clock ticking, making you feel the need to settle down and raise a family?...or are you being pressured into doing so?
Do you feel as though you are facing a future of possibilities and challenges....or are you seeing it as difficulties and failure?

Hope this helps, good luck!
