Source amnesia

Source amnesia is like when you forget where you heard or learned something. It's like when you forget who told you a story or where you read a fact. It's kind of like losing the tag on your shirt and not being able to remember where you bought it from. You still have the information, but you don't know where it came from. It's important to remember where you get your information from, so you can trust it and use it correctly. If you forget the source of your information, you could accidentally use it wrong or forget that it's not your own idea.
