(age : 35) You were in your old teenage room, looking at the objects you found a camera you looked at the photos where your best friend was, you started to cry knowing that you would not see him again because he died.

you close your eyes and feel something strange when you open your eyes you look at the room and see you're room from ten years ago. you screamed cause you're now 15 year. "What's going on?" It's your childhood best friend, Nao.

it is a dream or you really return 10 years back?
