The Subjective Effect Index (SEI) is a collection of articles designed to serve as a comprehensive reference work for the diverse range of subjective effects that can occur during an altered or non-ordinary state of consciousness. It has primarily been written to describe the effects of psychoactive substances (particularly hallucinogens) but may also be extended to other areas of psychonautics such as meditation, sensory deprivation, and lucid dreaming.

Each SEI entry consists of a systematic name along with a phenomenological description and analysis of the effect plus any other relevant information. SEI articles are deliberately written in a formalized writing style that seeks to avoid reliance on flowery metaphors or analogies, preferring instead to use ordinary language. This decision has been adopted in the hope that these descriptions will eventually come to serve as a universal terminology set that enables individuals to better comprehend and share experiences that are otherwise notoriously difficult to understand and convey.

The SEI currently contains over 200 entries that are organized into categories based on which sense they affect and their general behavior. Many of these effects are further broken down into levelling systems, subcomponents, and style variations that have been reported to occur between different substances and situations. Detailed replications, in the form of image and video examples, have been included wherever possible to supplement the text descriptions.

The contents of this index are based on the collective experiences of our contributors and various anecdotal reports collected from the internet. A curated archive of some of these reports can be found in our experience index.
