The Sleepwalkers were dream police that apprehended any beings that invaded the sleeping minds of humans. Sleepwalker was tricked by his long time foe known as Cob Web into entering the mind of one individual, Rick Sheridan, where he became trapped. After a few confrontations in Rick's dreams, Rick reacted by tearing off Sleepwalker's badge, which resulted in an odd situation further tying the two together. When Rick slept, Sleepwalker could materialize in reality or he could stay in Rick's mind and converse with him via his dreams.
