It's what Coleridge called the willing suspension of disbelief or poetic faith, for those moments where a story, no matter how strange, has some semblance of the truth, and then you're able to believe it.
Coleridge lo llamó suspensión  de la incredulidad o fe poética; momentos en que una historia,  por extraña que sea, tiene cierta apariencia de verdad, y uno se la cree.
