Some basic psychedelic themes covered or not covered with the three most comprehensive questionnaires used to measure psychedelic experience. A theme not covered by a particular questionnaire is marked with a grey cell. Bold items within single cells or within complex cells (cell collections that contain dashed-lines cells within them) indicate that these bold items taken together constitute a validated factor for the given subtheme. If there is more than one validated factor within a single cell, these factors are separated by square brackets.
