Is Tinkerbell and Peter Pan real? (Please say yes because ever since I was a child I loved to watch the movie)

Of course !! Absolutely yes !!!

Only if u believe! Believing can unlock doors to new places that we've never dreamed of! Believing can help u see beyond what others dont see! Keep believing, and never grow up!

Historically, yes; Peter Pan was based on one of the children of a family that JM Barrie was very close to (actually I believe that he wound up adopting them, but I'm not positive).

Theoretically? There's so much belief in him that the energy has to go somewhere...so it's entirely possible. I have memories, as a child, of seeing lights outside my window, but whether that was a fairy of not is still up for debate.
