I was with a group of friends in Angra dos Reis, a city in the state of Rio de Janeiro, Brazil. We were doing a shamanic journey at a house by the beach. We all had experiences related to interstellar travel. My experience was that the five of us unified our consciousness and became one single geometric shape that became a pentagram and we traveled in it to other galaxies. At the end of the evening, we decided to close the ceremony with a prayer at the beach. As we finished praying, I felt an urge to turn around and face the ocean, towards East. In that moment, we all saw what looked like a splash of white light in the shape of a sphere with tail way above the horizon in the sky. It flashed and disappeared.
