Dreams have always been fruitful ground for artists. Time spent in la la land allows imaginations to run free, and offers plenty to psychoanalyze. Light Grey Art Lab’s latest show, “Midnight,” explores the hidden meanings behind dreams. For the exhibition, 80 artists were asked to recall an unusually vivid dream and interpret it through a visual medium. Each work will include a brief synopsis of the dream alongside it. Bring your interpretation skills, and get ready to journey to the realm of the unconscious. You can also submit your take on the meanings of each dream via Light Grey’s website. The opening reception from 7 to 10 p.m. on Friday, October 28, includes music and refreshments.
