In the Amazon, there are some tribes who have ceremonies that can help them talk with the spirits of the ancestors, foresee the future and even talk to the other creatures in outer space. They do the ceremonies by using several tools and local foods that are considered sacred.

The result shows that it is actually not because of the strength of the magic of the ceremonies but it is actually the hallucinogenic effects brought about by a combination of compound DMT and B-carboline of the Ayahuasca potion which is usually used as the medicines in iowaska center to treat several diseases such as drug addictions and mental disorders.
