Ghost lyrics

So this morning, I wake up with a song in my head. In my mind's ear, it sounds a bit like Bob Dylan singing. They lyrics I can't recall are:

The things that you want back
are the things you can't get back
And when you get them back
You'll really want to know
But the things you want to know
You know you already know

So, probably, these aren't Bob Dylan lyrics, because, well, they aren't all that good, and he's a genius. Then again, genius or not, when you have a catalogue of a couple of thousand songs, some are going to be clunkers.

Still, I've googled bits and peices of the lyrics this morning, trying to figure out what song I'm hearing, and I can't find any songs that match. The tune, for what it's worth, kind of matches the opening of "Hurricane," and plainly these aren't lyrics from that song.

It's not at all uncommon for me to get a song stuck in my head, so stuck it dislodges all other attempts at thought until I dig out the album and listen to it. But how the hell am I supposed to do that with a song that, apparently, my mind has just made up?
