When I Called the Police, He Was Still Alive

The deceased was still alive when I first called the police. Three days later, she died. Surveillance, access control, chat records, and blood stains all point to me. But I have no memory of those three days. I only remember that after I woke up, everyone around me was urging me to confess. The psychiatrist said I might have dissociation disorder. The police said that I had a motive for murder. Friends said that before the incident, I seemed like a different person. I began to investigate the three lost days, only to discover that this was not the first time I had woken up. Every time I wake up, I will leave you with a warning: don't trust the person who helps you remember. The really scary thing is not that I have forgotten anything, but that someone is taking advantage of my forgetfulness to arrange a perfect murder for me. It wasn't until the end that I realized that the murderer was not setting me up. The past me is using the present me to force him out.
