DC's Knight Terrors event continues this week with the penultimate issue of the core series, as well as more of the character-specific spinoff series, being published today. And, as has become something of a tradition with this series, there's a direct link to Neil Gaiman's iconic horror comic, The Sandman.
In Knight Terrors #3 Damian Wayne and Batman's body - which is currently possessed by Deadman - travel to "the Hollow", a place described as being "not quite the waking world or the dreamscape", in search of the Nightmare Stone. While there, Deadman casually mentions that he has visited both the House of Mysteries and the House of Secrets. Spoilers ahead.
