Consumption of the flesh of Sarpa salpa, a type of sea bream also known as the “dreamfish,” can cause intense hallucinations. The hallucinations can be terrifying and often involve visions of aggressive and screaming animals, such as giant spiders or squealing birds. However, not all experiences are unpleasant. In 1960, National Geographic photographer Joe Roberts purposefully ate some broiled dreamfish and experienced hallucinations of “futuristic vehicles, images of space exploration, and monuments marking humanity’s first trips into space.” During the Roman Empire, Sarpa salpa was occasionally eaten for recreational purposes. The effects of dreamfish consumption can last for up to three days.
