The case of Felida X is studied by Dr. Azam. Felida suffers from periodical amnesia. In her primary state she was unaware of any actions that took place in her 2nd state, but she was aware of the presence of the 2nd state, but the amnesia is only present in the 1st state. In the 2nd state she remembers all of her actions while in the 1st state. While in this 2nd state Felida also presents changes in her character and affections. As Felida grew older the appearance of her second state increased in duration and her primary state became less and less frequent. Dr. Azam sees the amnesia suffered in the 1st state as the most important aspect of this case.
