frightmare

[Jonathan Lighter]

Not in OED, but Fox News just described a near-miss between airliners as a "frightmare at 30,000 feet."  
 
Zillions of RGs, most notably as the title of a celebrated horror film released in 1975 ("What terrifying craving made her kill... and kill... and kill...").
 
Rhetorical question.
