Can sometimes fear for their health, well-being, or lives when it would seem unrealistic. If they are too removed from the objective world, then they can have these suspecions, such as someone popping up and killing them. These can be relayed onto others as well, so Si might think some unhealthy act happened to a friend. They can also be suspecious of the people around them, talking about them, etc... which is when they display an outward appearence of being tired.
Can sometimes believe in what is not truely there. They can also seem lost without these beliefs. Because of this they may need some sort of dominating figure to be direct with them; forgetting about their beliefs. They may become afraid of their bodies and feel that their bodies are prisons. This leads them to become compulsive about their senses and how they relate to the outside world.
Trouble with identifying their identity. They may go to great lengths to deconstruct their entire outward appearence to put on a new "mask", and test out what is their "true" self. May not stick with any one thing for too long. May also be unstable in terms of their senses, which means that they can sink to an infantile form of hedonism; drugs, alchohol, etc...
May be unsure of what to believe in or where to go in life. If someone questions, they may loose their confidence. They will be careful with forcing others to belive in what they do. The may irrationally grab something and hold onto it if it makes them feel at ease. Anything to relieve them of the chaos.
Dreads closeness with others. May (wrongfully) believe that the way they deal with people is innappropriate. Can start to get neurotic ideas about relationships or the opposite sex. Can sometimes hide their fears with a child-like outward appearence as a boundary. Becomes scared when asked to voice what they really feel.
Can start to convince themselves that their moral values are sound even when they are off-based. Becomes angry when they are doubted by others. Incredibally resistant to faking or exaggerating emotions. They start to destroy all solid interpersonal relationships when they are not kept under close watch.
Becomes nervous when they don't know how they should feel and express themselves. Feels like they are slaves to proper social procedure. They have a hard time thinking other things that they cannot feel, so when they are unable to get some sort of emotional response out of people, they instinctively spark a reaction.
Can think that they know something when they really don't. Believes that they can tell what other people are thinking. They may put together or rearrange the facts in a completely illogical way if they are put under pressure.
