I believe it simply has to do with the wonders of the imagination. This song isn't supposed to make sense - it's about things that couldn't happen.
Let's start at the beginning. To a child, the imagination and a dream is every day life. But to an adult, the imagination isn't real. So the girl and her invisible friend ("But her friend is nowhere to be seen") goes off to dream on her own. The television is a bore because it's all the same...reruns, identical plots lines, etc.
Then the chorus? The adventures the girl goes through in her own mind - her own television program.
