Dys- comes from Greek and means "bad", "difficult" or "abnormal". It shows that something works with difficulty or differently from what is expected. It is the opposite of eu-, which means "good". For example, dyslexia is not a lack of intelligence: it is a different way of processing reading.
In medicine, dys- appears in many conditions where something does not work well, such as digestion, movement or emotions. In literature and science fiction, it names imaginary societies where everything has gone terribly wrong, the opposite of a utopia: 1984, Brave New World and The Handmaid's Tale.

"Dyslexia" is a neurological learning difference that affects specifically the processing of written language (reading, spelling). It does not imply low intelligence. Many highly intelligent people have dyslexia, including Albert Einstein and Leonardo da Vinci. It is a different way of processing language, not a global cognitive deficit.
"Dystopia" is not simply a gloomy or uncomfortable place. It describes a fictional society characterized by totalitarian control, environmental collapse, oppression, or systemic social failure. Classic dystopias: 1984 (Orwell), Brave New World (Huxley), The Handmaid's Tale (Atwood). The opposite is "utopia."
