A danger Forever Chapter 4
"What" yelled Firestar "Take Lionblaze, Dovewing and Jayfeather to the place. Where you found the scent."
When they reached a place Dovewing could smell heaps of Tigerstar's scent there was a small cat on the ground unconscious. They took it back to camp and when it awoke it said its name was Sky and it was thrown out of bloodclan because he believed in Starclan.
That night the entire clan was haunted by dreams in which they had to fight their worst enemies. Flood, Fire, Bloodclan, Tigerstar and Brokenstar.
They were told that if they died in the dream they would die in reality.
Sky being thought dead by Bloodclan woke up the entire clan.
But no one can stay awake forever or they wouldn't be able to fight, hunt or train at all and in sleep death would come eventually.
