The phrase 'clik clak' isn't something I recall from mainstream literature, but it totally reminds me of the eerie, rhythmic sounds in horror or sci-fi settings. Like in 'House of Leaves,' where the house itself seems to whisper and creak in unsettling ways—though not exactly 'clik clak,' the vibe is similar. Or maybe even the mechanical noises in 'Neuromancer,' where tech hums and clicks in a cyberpunk world. It's one of those onomatopoeic phrases that feels niche, like something a character might mutter in a surreal short story by Kafka or Borges.
I bet if you dug into experimental fiction or indie comics, you'd find it! There's a webcomic I love called 'Stand Still. Stay Silent,' where the sound of monsters moving is described in fragmented, almost musical syllables—'clik clak' would fit right in. It’s fun to imagine it as the soundtrack to some hidden, creeping danger in a dark fantasy novel.
