The great job of Mister Dream Doctor

Sandra has written to Dream Doctor because she suffers from lucid dream. According to her letter a few times when she was asleep, she dreamed with being awake. She felt, and she believes that happened, that she was walking around her bedroom. In her dream she tried to return to her bed and walked up, but she couldn’t control her own movements. After a while of failed disturbance tempts she could returned to her normal rest. She is not like a normal sleepwalker, she remember everything.
The answer from the Dream Doctor is really sad. Mister Dream Doctor founds Sandra’s sleep disorder very interesting, he calls her problem REM Behavior Disorder and he suggests that people who suffer from that illness has terrible accidents when they are asleep, so he sais that it is a good thing that Sandra has the possibility of being "awake" during her dreams because she can prevent her own accidents. Now, let me explain my point. What is wrong for me? First of all, I think that is quite difficult understand why people dreams with something if you don’t really know the person and your only knowledge about his life is a small letter. Second, and related with the firs point, here the doctor does his best, define a category for Sandra’s dream! But that action doesn’t really help her. I don’t believe that a medical name for a problem could resolve it. And I think Sara agrees with me, in her second letter she says that the Doctor give a great help to her. I like to think in that sentence like a nice irony. She says that now she knows that her problem is not a unique problem she doesn’t feel lonely anymore. Is like saying "because mostly of the people is afraid to the bullets, if I am in a gunshot I am not going to feel alone". Does it really matter?
