Lux-Formidulosusing

The thing or phenomenon that usually appears in the most standard horror media pieces regarding flashing lights with the intent of making you uneasy or scared and by building up the setting of those pieces to be ominous. This typically works at configuring the subject, even if they have no phobias to do with such, or anything at all, nor any past instances of anxiety or other types of fear towards many things, especially flashing lights.

Example 1: "The Lux-Formidulosusing that this game uses really pulls you into the setting. I love little details like that!"
