Non-ordinary States of Consciousness, produced by some specific kinds of psychoactive agents, as, for instance, the ayahuasca, propitiate visions, treated in this work as mirações. In the initial stages of the experience, these mirações are often formed by luminous and symmetrical geometric patterns, zigzags, latticeworks, cobwebs, and spirals, among others. In more advanced stages, these images can turn themselves into several objects and scenes, where the influence of culture will play an important role. Analogous visual patterns can be found in artistic works, ever since the pre-historical rupestrian paintings, and this fact allows the conclusion that such a production is, in some form, related to the Non-Ordinary States of Consciousness. In fact, the same visual patters can be found in the art of Indians and present day artists that use such kind of psychoactive agents. The mirações from NOSC are often considered spiritual or mystical experiences, since are felt as actual experiences of “another world”, and such experiences can only be translated to this world, the objective, material and daily world, in a descriptive and symbolical way. Among the several images that can appear in the mirações, this work aims at investigating spirals and vortices. It approaches some of the meanings that are commonly related to these elements, as well as some transformations and adaptations that they are bound to, depending on the local culture. Moreover, this work collects some spirals and vortices occurrences in nature, science and art history, aiming at presenting the great influence that such images may have on the imagination, knowledge and art productions.
