Which horror game should I treat myself to?

I'm replaying SH1 and feel like delving further into horror on PS1. I've already played/beat the RE games and Dino Crisis. And SotN if we're counting horror adjacent lol. Right now I'm considering:

• Clock Tower
• Parasite Eve
• Koudelka
• D
• Echo Night

Kinda leaning towards Clock Tower or Parasite Eve but I know they're two very different games. For frame of reference, the early RE games, Silent Hill games, and Fatal Frame games are my all time favorites.
