Many of the books I read, include mythical or fantastical creatures. Orcs, ents, elves, dwarfs, Martians, Vulcans, and the like. Most people likely believe these creatures are imaginary. Possibly people believe they exist as cryptids, a creature for which there is mere suggestion and little proof of existence... like Sasquatch or the Loch Ness Monster or the Pittsburgh Tunnel Monster, which feeds upon faster moving traffic which explains why everyone in the 'Burgh slows down immediately before entering one of our tunnels making the traffic jam cascade behind them.
In a recent spewing, Phil Robertson opined on an imaginary violent encounter with an atheist in which the atheist's wife and daughter were raped and murdered, followed by the castration of the atheist. Throughout this foul reflection, Robertson follows the old motif that the atheist cannot oppose such activity because he, being an atheist, has no basis for any moral judgment. The perpetrators of the evil against the atheist say in the midst of their attack, "But you’re the one who says there is no God, there’s no right, there’s no wrong, so we’re just having fun."
