"Turn into" is a phrasal verb, which means for something to become something else. To be transformed from one thing to another. It's commonly used when something escalates or changes from one thing to another. Or if the function of something changes from one thing to another. Ex: The discussion turned into an argument when Jake made a rude comment. Ex: We turned the spare room into a music studio. Ex: The chilled hangout quickly turned into a party.
