So I'm working on my second novel now which is a thriller based on Lucid Dreaming. I have the protagonist lucid dreamer and the antagonist lucid dreamer. I just became aware of the terms "Dream Walker" and "Night Stalker". My question is this: if you guys were reading a book and it started talking about the "night stalkers", would that sound really childish and lame, or would that go with the flow of the book if it's based on lucid dreaming?

Thanks for any opinions.

Not sure if this is off topic, if so then my bad.
