Hawkman finds himself in a city of iceboxes, among cold people expecting to battle the Fire People, their mortal enemies. One of them feels sorry for the birds there who suffer because of their battles, so Hawk manages to escape from the ice box he is in and attempt to help the bird creatures. If he fails, the battle will result in hot and cold waves that would kill them all. But try as he will, Hawk gets the worst of it....one minute hot, the other minute cold, until he believes that he is a thermometer!; Dr. Mid-Nite finds himself in a world where germs are the lords of creation and he saves a man they plan to save for future study. The humans there convince Mid-Nite that his former life is all a dream, but he uses his scientific ability to try and fight the Germ People. He develops a noxious gas to use on the Germ People, but it fails to work, and he is convinced the other humans are right. But his instinct to fight remains strong and he battles them with his fists until one of the Germ People with the plague enters, blaming it on Mid-Nite. He is then convinced that he is a living sickness.; The sputtering of a 4th of July sparkler arouses the interest of not only Green Lantern, but astronomers as well in this dream world, who seem to think that the sparks are actually new stars being born. The Emerald Crusader tells them no, but they think he is mad. Then several crooks steal the sparkler and the Emerald Crusader chases them through maddening situations, and finally he spots the astronomers below watching him (holding three balloons by strings), and he suddenly feels that he is the Sun and the three balloons are his little planets!; The Crimson Speedster finds himself plunged into a dream world of funny animals who talk and act as if they are human (humans are enslaved), but the Flash says otherwise, so the animals try to prove humans can't talk. Fact is the animals can't hear other humans, just the Flash, but Flash can hear men speak. The animals' law states that if a human can beat one of the animals in a race, enslaved humans will be freed. He races a frog, but when his feet grow large and heavy, and a series of calamities occur, the Scarlet Speedster loses. Flash now believes he is a laughing stock.; The Atom awakens to a world where the beings have umbrellas for arms and clocks for heads. Just then, Atom sees large crooks heading into a bank, and he attempts to combat them. But he finds out that the rain is shrinking his size and he falls into the water. He heads back after the thieves, only to discover that he has now grown tremendously, and he reaches up to a cloud and pulls a chain to turn on the sunlight, hoping it will shrink him back down to normal size. Catching up with the thugs, the criminals begin to wring him out, convincing the Mighty Mite that he is a sponge!; Johnny arrives in the Land of Already Equipped and spots an artist with a brush for a hand and an artist pallet for a head, painting a picture of a young lady, whose head was a bowl of fruit! Johnny thinks that's normal, while the T-Bolt thinks he is nuts! Others in this world are also weird in appearance, but considered normal. Some human crooks get a magician to hex people into looking "normal", and Johnny sends the T-Bolt to capture them and the magician who hexed people. While other JSA members were driven insane in their dream worlds, Johnny was driven sane!; In the Brainwave's lab, the JSA members are stirring restlessly in their dream-induced states. As the villain leaves the lab, the JSA members begin waking up, acting out their dreams. Johnny has had enough of this and calls for the T-Bolt to come and figures out what to do to restore them. Brainwave returns with his gang to see the JSA in their state. Johnny and the T-Bolt storm in and Johnny wades into them, fists flying, while the T-Bolt uses an electrical shock to restore the JSA back to themselves. Furious, the JSA wades into the crooks and mops up, then T-Bolt explains what happened.; Hawkman brings a newspaper ad to the attention of the members from a Forest Malone, who wants them to participate in a never before done experiment for the good of humanity. They visit Malone and viewhis "dream recorder," a machine that will allow one not only to graph the electrical emantions from a person's thoughts as they dream, but to also translate those thoughts into pictures! The members agree to an experiment, they sleep and then Malone reveals himself as the Brain Wave, bragging that the machine is really a "dream inducer," which he plans to use to drive them totally insane.
