The problem of unconscious in philosophy and medicine (Z. Freid, K. Yung, E. Fromm)

The unconscious is a manifestation of the internal state of the human psyche. This is a unique world, covering various spheres of spiritual life and personal activities. This is a unique mental state of hers when "dark or vague sensations, either partially conscious or completely incomprehensible," manifest themselves as they are beyond the "threshold" of consciousness. Everyday experience shows that a person really breaks into certain feelings and vague thoughts arise, it is unclear where they are coming from.
