Eldritch Is Stronger Than Simply Strange
Strange and mysterious capture only part of the meaning. Eldritch usually adds an eerie, uncanny, or supernatural quality, which is why eerie, uncanny, and otherworldly are often closer.
For horror or gothic writing, sinister, macabre, ghostly, and chilling let you choose the exact source of the disturbing effect.
