When Freud was alive, he believed that neurosis and hysteria created ideas and other materials that created anxiety among human beings that took place in the unconscious mind. Freud also believed that these ideas were too difficult to think about using the conscious mind, but that the ideas still needed to be expressed in some way, shape, or form. This idea along with others helped create psychoanalytic theory. This theory provided methods that helped cure mental illnesses and explain other human behaviors. In today's society, this exact theory may not be accepted, because in the world we live in now, many people need evidence or hard evidence to agree with different ideas. The whole idea of ​​neurosis and hysteria may still be relevant in today's society, however, under a new name. In our generation, doctors, philosophers, and psychologists might think of these unconscious anxieties as specific mental desires, separating them into different categories (such as obsessive compulsive disorder, OCD) rather than simply grouping them under one broad category such as OCD.
