Google DeepDream emerged in 2015 as a visualization tool for understanding how deep learning networks interpret images. By amplifying patterns the AI recognized—most famously dog faces and eyes due to its training data—it produced hyper-saturated, kaleidoscopic visuals that the internet quickly dubbed 'AI hallucinations.' Beyond its scientific roots, DeepDream became a staple of internet culture for its psychedelic aesthetic and unsettling imagery. It is commonly used in memes to represent sensory overload, a 'bad trip,' or the often bizarre and glitchy way artificial intelligence perceives the human world.
