Illusion

Life isn't same for everyone. Sometimes we met some people who isn't real. Those persons are neither dead not alive. Some people have the ability to make illusions. Is this an ability or a curse? Am I cursed? But why? What would happen to you when you will deeply in love with a person but in the end you will figure out that he is just an illusion created by you?

I saw mom and dad getting burnt alive. The voices and screams are still in my head. And my twin sister Anna never left me alone. Not even after her death. She always stayed with me. How could a dead person stay with someone who is alive?
