Cold War Kids - Cryptomnesia Lyrics

The song is referring to the psychological phenomenon known as Cryptomnesia, which is defined as "a forgotten memory that returns without its being recognized as such by the subject, who believes it is something new and original. The person isn't deliberately engaging in plagiarism but rather experiencing a memory as if it were a new inspiration." So basically, Nathan Willett is explaining how he's experiencing someone else's memory, or possibly his own, in the song.

i.e "I feel your Cryptomnesia, cryptomnesia." and "You can't dream so slow, don't check the index for reference..." because the memory has been lost in translation.

i honestly couldn't tell you what the song really means. I haven't put much thought into only that every time i hear this song i feel something. Even if its something small this song evokes many emotions and i love it for that.
