Freud says that the origin of all mental disorders are experiences in childhood. By saying that in order to learn the effects of these experiences, it is necessary to look at the subconscious instincts and symbolic images in dreams. He lays the foundations of psychology and changes the whole view of today's people towards science. Even today, his theories are still being discussed and have not been disproven yet.
"If a someone is looking at a place, there is something he is interested in. If a person is not looking at a place at all, there is definitely something he is interested in."
