Jemma Redgrave is on the verge of marrying caddish Mark Greenstreet. Spending the night in her spooky old family mansion, Jemma stares into a mirror and begins experiencing terrifying dreams. She sees her past, present and future in a Bosch-like kaleidescope. And without knowing how or why, Jemma drags American tourist Kathleen Wilhoite, herself the victim of a troubled past, into her nightmarish visions. Its powerhouse opening sequence aside, Dream Demon tends to be rather slow going, despite some very convincing special effects.
