One of the primary themes of “Before I Go to Sleep” is the exploration of identity and self-discovery. Chris’s condition forces her to question her own identity and her relationships with others. As she tries to piece together her past, she begins to realize that her memories are not always reliable and that her perception of reality is distorted.

Each day, Chris writes notes to herself in a journal, trying to piece together her life. She also sets up a complex system of reminders and clues to help her remember important details. However, as the story unfolds, Chris begins to suspect that something is not quite right. She starts to experience strange and unsettling events, and her memories of the previous day begin to resurface.

The movie revolves around Chris (played by Nicole Kidman), a woman who suffers from anterograde amnesia, a rare condition that prevents her from forming new memories. As a result, Chris wakes up every morning with no recollection of her past or her identity. Her husband, Tom (played by Mark Strong), takes advantage of her condition and manipulates her into believing that she is his wife.

James McAvoy’s performance as Dr. Robert Searle, a neurologist who becomes Chris’s ally, adds an extra layer of tension to the story. His character’s motivations are complex, and his relationship with Chris is multifaceted.

The movie also explores the theme of manipulation and control. Tom’s manipulation of Chris raises questions about the nature of consent and the ethics of controlling someone’s memories. The film highlights the dangers of exploiting someone’s vulnerability and the consequences of playing with someone’s memories.
