Were the parables told by Jesus based on actual historical events or were they purely metaphorical teachings meant to illustrate spiritual lessons?"

The Gospels record many parables spoken by Jesus, often used to teach moral or spiritual truths. Some of these, like the parable of the prodigal son or the good Samaritan, contain vivid, lifelike details. This raises the question: Were these stories based on actual historical events and people known to His audience, or were they entirely fictional narratives created to convey deeper lessons? I’m curious how different traditions or scholars interpret this — are there clues in the texts or historical context that suggest one view over the other?
