7. Plato tells a story of prisoners, chained in a cave, never seeing the real world, just a puppet show in shadows. When one of the prisoners gets out of the cave, he is shocked and scared by the real world. He wants to go back into the cave. What message was Plato trying to convey with this Allegory of the Cave? What was his point?

He is saying that human perception is not true knowledge (to the prisoners the shadows are reality) and instead, real knowledge can only come via philosophical reasoning.
