Shape Shifter Mind Warp 5

My name is Todd Aldridge. At least, I think it is.... Where did I go? I don't remember much about the night I disappeared. One minute I saw the strange light in the sky. The next minute I saw a strange light in the sky. The next minute I woke up in the hospital. The thing is, it wasn't the next minute. It was nine months later.... What happened to me? Some people think I was kidnapped. Others say I was abducted by aliens. I don't know what to believe. But I know this: I'm not the same as before. I've changed. And I keep changing. Suddenly I make myself look like different people. Anyone I want. The only problem is, I'm forgetting who I really am. Who am I?
