Your unconscious mind is driven most by Self-protection
Whether you know it or not, your unconscious mind is defending your internal emotional experiences. It acts like an emotional dam that helps you keep things in check. One reason for this could be that you have a deeply-rooted fear of being flooded by emotions. In response, your unconscious acts in the opposite manner, by protecting you from unpredictable, emotional tidal waves.
While this tendency might be useful in some circumstances, it may also at times make your emotions hard to articulate or grasp. And that can lead to some frustration.
Since you tend to appear level-headed to others, they feel they can count on you for sound opinions and advice. Another benefit of your unconscious drive is that it allows you to remain calm in the toughest of situations. This can be a real benefit for you during business negotiations or personal arguments because you're not apt to say damaging things that you'll have to apologize for later.
The only hazard with this drive towards self-protection, is you might filter out good emotions as well as the bad. That can leave you feeling like something is missing, something you can't quite place.
But ultimately, your unconscious is wise and will know if there is a time in the future where it would be beneficial to be different.
Though your unconscious mind is driven most strongly by Self-protection, there is much more to who you are at your core.
I'm not sure how accurate this is, since it's pretty easy for me to burst into tears, and get angry, and be emotional in general, but maybe I am kind of distant with people. *shrug*
But I do shy away from conflict. This is because I used to be obnoxious until I was 15. *grin* So now maybe I'm not obnoxious enough.
