Hello, I believe there is a vortex on the campus of The University of the Incarnate Word. Specifically at the blue hole. Many students have experienced different phenomena, from supernatural occurrences, to feeling a change in time. I myself am sensitive to energies and have felt a great deal of energy from this area. I also have been researching and have found multiple sources stating that there is likely multiple Leylines running through San Antonio and this may be an intersection. – M
