Okay kiddo, imagine you have a book of bedtime stories that your parents read to you every night before you go to sleep. Now imagine there are some stories that are not in that book, but your parents still tell you those stories anyway. Those extra stories that aren't in the book are kind of like apocryphal stories.
Now, let's talk about prayers. Prayers are like talking to a special friend who you can't see, but you believe is listening. Sometimes people write down prayers in books, like the Bible or the Quran. However, sometimes people find or make up prayers that aren't in those books. Those prayers that aren't in the official books are called apocryphal prayers.
It's important to remember that while apocryphal prayers are not in the official books, they can still be very meaningful to the people who say them. It's like a secret handshake or a special song that only you and your best friend know - it's not official, but it's still important to you.
