Finding ‘the weird’ in psychedelic art
The concepts of altered states and psychedelia creep in to a great deal of visual art. According to Lewis-Williams, some early forms of Palaeolithic rock art may have been shamanic in origin, and represent forms seen during visionary states. 18th Century works such as Fuseli’s The Nightmare (1781) depicted the ‘old hag’ phenomenon, a type of hypnagogic hallucination that is experienced on the threshold of sleep, during which a person feels as though a daemon or other supernatural entity is suffocating them.
