When something happens bewilderingly, it makes you feel lost, usually because too many things are going on at the same time — too many choices, too many signs, too many people talking. You use it about the way a thing feels, not about a person: a shop can be bewilderingly full of brands; a city can be bewilderingly loud. It is a rather bookish adverb. In everyday talk people more often say “so confusing” or “I didn’t know where to look.” Though actually, writers like it because one word carries both the confusion and the “too much” feeling. You will meet it in reviews, news, and stories more than in the playground.
