The “Other Nightmare” is a male Nightmare.
Description[]
One night in 1945, Mickey's Nightmare was late to his bedside, leading to this uglier, meaner troll of a Nightmare attempting to take over the duties of scaring Mickey. He was, however, shoved off by Mickey's Nightmare, who finally arrived just in the nick of time and apologized for his lateness. Oddly unperturbed by all this, Mickey agreed that it was quite unpleasant to have a stranger butting into his dreams like that.
Behind the scenes[]
The Other Nightmare appears in the 1945 comic strip Cheese-and-Crackers Nightmare.
