I'm not comfortable with categorizing my own work, but I don't mind if others talk about it in relation to genre as long as they don't try to hold it up to some genre standard.

Your first thought is often the best one. You know, the one that felt too weird or silly or stupid. Trust your imagination - it knows what it's doing.

Some of my other stories are talked about as fantasy, some as horror, and some aren't talked about as genre at all. And the same story will be labeled differently depending on country.

If you want the reader to accept the premise as a given, then being specific is vital. This is what I'm after; I want the reader to accept the setting and the mindset of the characters, so we can get on with the story.

All my stories and worlds spring from the basic principle of being a slave to the premise, to follow the consequences wherever they may lead without taking any easy or comfortable ways out.

Worldbuilding to me is taking the consequences of an idea.

I don't go out of my way to write Weird Fiction, or in any other genre. Some of my stuff easily slips into the Weird slot.
