Based on the question it would be safe to say that the psychologist that John went to go see is a Psychoanalyst. These doctors are experts in diagnosing and treating different mental disorders by working with what people go through while conscious and unconscious.
Usually by interpreting dreams and figuring out what may be the cause of them, to then figure out what that person may be repressing and find a solution/treatment.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
