Even though the same dreams have different meanings for different people, it is possible to accurately interpret them. By simply working through a person’s relationship with an object, it is possible to understand the meaning of a dream.
In the example of Freud’s patient. Freud knew that his patient frequently referred to his sister-in-law as a dog. Therefore, when the patient dreamt of strangling a dog, Freud was able to accurately infer that his patient was harbouring a secret desire to kill his sister-in-law.
Some methods of dream interpretation can also reveal the individual’s personal dream vocabulary. For example, hypnotherapy allows the dream interpreter to interact with the subconscious mind. He or she may ask questions and get the dreamer to explain their personal dream vernacular.
