Yes, it happens and it catches many website owners off guard. Traffic can drop because Google updated its algorithm, meaning Google changed the rules for how it ranks websites. A competitor might also have improved their content and pushed your pages down. Seasonal changes can cause drops too, especially for businesses that are popular only at certain times of year. Sometimes a technical issue like a broken link or a slow loading page is quietly hurting rankings without anyone noticing. So do you think website owners check their traffic data often enough to catch these drops early?
