H25 limitation for Dread requiring sensing the object to react to it.
B262's full-value Dread in the Vampire template for Janos Telkozep lacks this, so coming within a distance of a holy symbol or garlic or running water repels him even if he is not capable of detecting it via a sense other than Dread
This presumably removes the benefit of being able to sense things (like running water) via Dread
