I am 18 years old and have always had a very active imagination. When I was little I could create entire worlds that I could play in with imaginary friends, people and animals. Now it's gotten worse. I seem to prefer the idea of my world inside my head. Even during the day my mind travels as I sit in class I could be out on a boat in the middle of the ocean. (I want to be a marine biologist and have since I was three) I have a few other eccentricities such as: twitching, not paying attention well, and losing myself in conversations about sea life. But I am most worried about the stories that go on in my head. I try to find ways to escape real life and I can talk to the people I make up in my brain. It's as if I am the main character in a movie that I write as I go and never really leave. I do actually speak out loud to my characters when no one is around. Please let me know if this is normal. I can give more details if necessary.
