Visual effects of mescaline and hypnagogic imagery (images experienced just before sleep) show more than superficial similarity, suggesting that comparing the two states may illuminate underlying processes. Early observations by Weir Mitchell (1896) noted this resemblance, and the authors' own research group began investigating after a subject described mescaline visions as similar to pre-sleep imagery. Findings from a prior study on hypnagogic imagery (McKellar and Simpson, 1954) and further mescaline experiments support the connection.
