“Fairy tales are more than true: not because they tell us that dragons exist, but because they tell us that dragons can be beaten,” said Neil Gaiman, in a quote that frequently pops up online. Maybe so.
But, also, remember that dragons can beat us. This is equally important and equally true. Danger is part of what is real, of what is true. We can lose, as we can win.
Otherwise, beating our dragons would be meaningless. As would be losing to them. There would be no heroism, no dignity, in either win or loss.
Fairy tales remind us of this, that life is an adventure, a quest. So maybe fairy tales are true because they tell us dragons exist. We just need to be reminded of that, now and again.
