I am currently working on a science fiction novel series. I am Twilight Zone fanatic and have conjured up many ideas, not from the TV shows themselves, but the idea of a parallel/mirror world that is non-detectable to the protagonists through strange, unexplainable occurences here on Earth. I have entertained several title ideas; however, none are inspiring or "catchy." If anybody has suggestions, please help me out. Not only do I need title suggestions, but explanations for the title. Hoping not to lose my credibility as a "non-orginalists", (that's a two dollar word) I am presenting simple but entertaining stories with majaor shock value at the climatic point as well and the "duh" moment, similar to Rod Serling The Twilight Zone.
