Is our life a fiction?

It took me hours to finish a film of called Ruby Sparks.  To be honest, I did not really like the film. I always let my mind wander when I was watching it.  During These days Recently, I spent for about three months in a strange place.  Things change a lot when I leave the familar things.  Sometimes I feel like my life is a fiction.  It's not real.  When I woke up, I didn't know who I am was and what I do (did?) here.  It will take me for a while to realize I am alive.  It's weird.  I met some new friends here. We spent a little time together then we said goodbye to each other. We exchanged our communications such as wechat or QQ or something else.  I always feel that if I close these things, maybe I will disappear, in a sense, for them.  Were they my fiction, too?  I don't know.
