In "The Dream Killers!", the Challengers of the Unknown confront a chilling mystery in Boulder, Colorado, where citizens can't sleep for fear of skeletal figures in their dreams. When Tino, Red's brother, becomes paralyzed by nightmare terror, the team uses Prof's dream-visualization machine to dive into his subconscious—only to discover the entire city is under siege by dream-born horrors. With Jack Sparling's stark, expressive art bringing the eerie black-and-white dreamscapes to life, and Neal Adams' haunting cover capturing the dread, this 1969 issue delivers a surreal, suspenseful journey into the mind’s darkest corners.
