In The Dream Hotel, Laila Lalami imagines a world where the government has access to data about people's dreams … and uses it to decide if someone is likely to commit a crime. When Laila's protagonist, Sara, is flagged as high risk, she’s sent to a retention centre and subjected to constant surveillance. Laila talks to Mattea Roach about her interest in dreams, the dangers of invisible data collection and her multilingual journey to writing.
