The two young belgian women who conceived and performed "Laura's Dream" at Chevy Case Community center on Tuesday and again last night, have worked with the giants of contemporary epic theater. Kristel Stefens is an actress trained by Grotowski and Robert Wilson; Claudia Minne danced with Maurice Bejart. The first image in their movement and voice collaboration, though hardly original, had something of the shocking grandeur of their mentors'art.

Stefens and Minne were coiled up together, seemingly nude and encased in a plastic bag. Since the curtain was up when the audience entered the theater, and the performers began almost immediately, one couldn't tell whether the amorphous, shiny bodies were performers or props. Gradually they began to move, rolling across the stage like Siamese twins in a placental sac, and emerged fitfully from their casing to utter the newborn's yell.

What followed was an association game based on the character of Laura, the crippled girl in Tennessee William's "The Glass Menagerie," whose fantasies with a collection of glass animals are briefly interrupted by a gentleman caller. The long-legged, pliant Minne danced dreamy passages of free-form ballet to Mozart, Beethoven and Schubert music for flute and piano. The sturdier Stefens played with a bag full of toys, spoke a few lines and gazed after the caller (Bob Sacheli) as he crossed the stage carrying a red rose. Williams' play used a concise dramatic structure to focus on Larua's dream life; Stefens and Minnie, following Whims, made the action dull and vague.
