Is Lily a real character in Black Swan?

No, Lily is not a real person. Nina did not kill the actual Lily. Instead, Lily represents Nina's inner turmoil and darkness. Throughout the film, Nina experiences hallucinations involving Lily, reflecting her psychological struggle. As Nina's mental state deteriorates, she begins to project her insecurities onto Lily, perceiving her as a competitor or threat. This is evident when she sees her own reflections in others, contributing to her growing sense of paranoia.
