You can only grab this achievement during Rakan's chapter. After you have been sent to the hospital a second time, you will be chased by a group of faceless beings. Once you have escaped them and went down the stairs, you will come upon more hospital rooms. Don't grab the key in the admissions office or you won't be able to get the tape! Instead, head to the Medical Records Dept. room. Its on the right side of a hallway you go down. There is a payphone close to it. Inside the room will be a tape on a desk that you can play revealing Rakan's mental health and your achievement!
