Synopsis:
Tino reports to the other Challengers that he is being chased in his dreams. They aren't worried until he begins bleeding in his sleep. Prof builds a machine that allows the team to view Tino's dream and allows them to see his pursuers.

While Prof works on another machine that will allow the team to enter Tino's dream, the Challs learn that other people in the city are also plagued by the same dreams. When Prof's work is complete, the Challs enter Tino's sleeping mind and discover that an alien brain is responsible for the nightmares. They destroy the brain allowing Tino and the other victims to sleep normally again.
