Your subconscious is showing you the truth about how you are feeling about life situations, which may be totally different than the situation in the dream. The body needs an emotional release because of issues not dealt with on a conscious level. Issues like suppressed anger, grief, agony, or emotions that have built up from not being expressed. Tears may also represent vulnerabilities. You are not the ice Queen/King that you let on to be.
