Effect Categories - Multisensory Effects

Multisensory effects are defined as any subjective effect that directly alters two or more senses at a time.

It is worth noting that although hallucinatory states may affect multiple senses, they are typically not categorized as multisensory effects unless they consistently affect multiple senses every time that they occur. For example, while experiences with autonomous entities may sometimes have a tactile component to them, more often than not they are primarily a visual experience and are therefore classified as such.
