The song is called "Floating". and rightfully so. it gives off the vibe of an adventurer floating through the cracks of time and space as they swim through the ether only to find an old friend who needs their help. The scratching to me symbolizes time and space only tearing further and further apart at the seams.
I hope this saga will be long enough, coz I love Ravenloss/Pellow Village saga, definitely the best one in entire game. And this soundtrack is AWESOME!!
