They hide themself by becoming lost and trapped within their own mind. And the lies they tell, spreads diseases within their own physical body.
This happens when there has been a traumatic experience and the individual is unable to process the data.
Because of the Terror and immense pain they have experienced. The individual forgets and selective remembers what they want to hide their shame.
They become lost and trapped within their own mind, spreading lies to reinforce their fantasy to keep themself safe.
This is how they protect themself from the danger that is outside of them. By forgetting what happened and puts in replacements/distortions to help them cope with everyday life.
