Neil Gaiman and Dave McKean recall the Sandman's 1989 origins:

"They said: make it your own. So I started thinking more mythic – let's have someone who's been around since the beginning of time, because that lets me play around with the whole of time and space. I inherited from mythology the idea that he was Morpheus, king of dreams: it's a story about stories, and why we need them, all of them revolving in some way around Morpheus..."

"Years later, Karen said: "Of course, Dream is you." I said: "No, I've got a sense of humour." I suppose he looks like me, though. But that's one of those peculiar things where you gradually start to look like your dog."

When Alan Moore Met Hellblazer

In a 1993 interview with Wizard Magazine, Alan Moore revealed that he had met John Constantine in real life:

“One day, I was in Westminster in London—this was after we had introduced the character—and I was sitting in a sandwich bar. All of a sudden, up the stairs came John Constantine. He was wearing the trench coat, a short cut—he looked—no, he didn’t even look exactly like Sting. He looked exactly like John Constantine. He looked at me, stared me straight in the eyes, smiled, nodded almost conspiratorially, and then just walked off around the corner to the other part of the snack bar. I sat there and thought, should I go around that corner and see if he is really there, or should I just eat my sandwich and leave? I opted for the latter; I thought it was the safest. I’m not making any claims to anything. I’m just saying that it happened. Strange little story.”
