The work “Dim” consists of a real metal venetian blind and a video at the lower part of it. In video, through the plane (venetian blind) blocked in between, the camera pans at low-angle slowly from left to right, making a horizontal scan observation toward the sleeper/insomniac. As the title’s multiple suggest: vague situation, unclear light, memories which can hardly recall and abbreviation of the word dimension ── here is a possible border where sleep and wake intersect.
