The Hounds of Tindalos by Frank Belknap Long

4.0

Gang, this is why we microdose before taking enough drugs to cross the spacetime continuum.

A fun little romp of a man who manages to get so high that he's able to travel back to the space before spaces and the time before time and in the process catches the ire of a group of extremely alien pursuers.

The eponymous hounds are anything but doglike. They're never fully described but are referred to with angular and sharp language. Appropriately, they can only travel through angles and are befuddled by smooth curves.

Cue our protagonist plastering up all the corners in his wall in a futile attempt to stave off the beasts(?)

I like this one for just how alien the antagonists are. It's also really not clear WHY they're so gung ho about killing the protagonist. Their reasons are entirely alien, through and through.
