Before proceeding too much further, however, it should be noted that horror and fantasy do have qualities in common. They both require that readers engage, according to W.R. Irwin in The Game of the Impossible: A Rhetoric of Fantasy (1976), in a conspiracy that agrees to suspend the rules of everyday (8-9). Readers must invest strong psychological belief in the literary worlds that are presented. Gary K. Wolfe, in his essay “The Encounter with Fantasy” (in Schlobin ed.), correctly points out that this is more than the “willing suspension of disbelief” that Samuel Coleridge first observed and so many scholars have slavishly followed since (including J.R.R. Tolkien in “On Fairy-Stories”). —FANTASY VERSUS HORROR In Survey of Modern Fantasy Literature via http://wpl.lib.in.us/roger/F-VS-H.html

I tend to look at “willing suspension of disbelief” more in terms of regression and the suspension of reality-testing.
