How to understand the sentence "The palm of your hand suddenly grows tangled curve" in Faye Wong's Time?

Time flies is a superstition, and superstitious people will believe that their palm prints indicate fate.

The meaning of this song is that you can't guess your own destiny, and the sudden increase of tangled curve in the palm of your hand increases the uncertainty of your destiny. We know that palm prints are generally unchanged. If you are hesitant at the crossroads of life and have a dream of looking at the palm print, the moment you reach out, your palm print will suddenly tangle. Will you have more regrets when you wake up?
