On a warm night in late fall at the Rainey Institute on East 55th Street in Cleveland, Ananias Dixon leads a group of roughly 35 acting students mostly in their 20s and 30s through a fun, high-energy warm-up exercise. It’s another free Community Mode Monday for D.O.C. Studios, and Dixon, co-director and an acclaimed Cleveland actor and theatre teacher, dives into this movement activity known as the Golden Light ritual.
