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 you believe! Believing can unlock doors to new places that we've never dreamed of! Believing can help you 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 or not is still up for debate.
