Traveling...traveling...

I know what it's called (mondegreen) when you mishear the lyrics to a song ("'Scuse me while I kiss this guy"), but what do you call it when you misremember the lyrics? I misremembered a line from Rihanna's "Shut Up and Drive" as "chamois killing machine." WATCH OUT FOR THAT SNUGGIE!

( Long sleep, weird dreams )

I wonder what it all means? (Could me starting to have read Dan Brown's "The Lost Symbol" yesterday have anything to do with it? Hmm...)
