What is a good analagy for cypotysm?

A good analogy for cryptomnesia is a "tip-of-the-tongue" experience. When you have a "tip-of-the-tongue" experience, you feel like you know something, but you can't quite remember it. You may be able to remember some details about it, but you can't quite put it all together. Cryptomnesia is similar to a "tip-of-the-tongue" experience, but instead of feeling like you know something, you believe that you have come up with an original idea, when in reality, you have subconsciously remembered it from something you have seen or heard in the past.
