Source Confusion
Source confusion refers to the memory of information as being obtained from one source when it was in fact obtained from another. For example, believing you witnessed something in the past when in reality you read about it, or believing someone told you something personally when you really read it on their social media page. It is problematic when recounting an event and claiming to remember something you didn't witness. For example, thinking you saw a gun during the commission of a crime, whereas in reality you were told of the gun after the fact.
