Who am I?

I don't know anything about myself, not my name, age, or where I'm from. It's as if I just appeared on the earth one day with no explanation. There's a girl, she comes to me in my dreams and she seems to know me. She calls me Caleb, so I guess that's my name. I have a lot of questions and I'm sure she's got the answers . I've got a little problem though... Nobody can see or hear me. Well, mostly everybody there are three people who definitely can. For a little while I have a nice and normal life with them. Well... about as normal of a life you can have when the only people who can see you have some not so normal gifts. But suddenly she comes to me with an urgent message: that I must find her before it's too late and that somebody's coming for her. So now with the help of my friends I'm going to find her and I am going to remember.
