Samenvatting

A substantial percentage of normal people has been documented to report hallucinatory experiences. We investigated the multi-dimensionality of such experiences in 243 subjects from the normal population who completed the Launay-Slade Hallucination Scale. Principal components analysis with oblique rotation was performed on the data. Three factors were obtained loading on items reflecting (1) tendency towards hallucinatory experiences, (2) subjective externality of thought, and (3) vivid daydreams. An additional exploratory factor analysis revealed highly similar factors. The results support the concept of hallucinatory disposition as a multi-dimensional construct.
