"I was up walking and you were the shoes/bored with the thoughts that you thought I could use/islands were made of brick stone and shade/where deaths only rest of laughable tunes" - I think this part uses walking like before "and i'll walk till my legs are broken" to mean continuing on regardless of the fear to make sure the "mind still grows". If you are using someone else as the shoes while walking, it could either be talking about how there are other people around us to make it easier, but we get bored with the personal thoughts other people say because they feel we can use them somehow in our 'walk'. At this point, when you get bored, 'islands are made of brick stone and shade' or houses as we isolate ourselves inside. And if the phrase 'deaths ONLY rest' (showing an acceptance of mortality by calling death ONLY rest and therefore not really that important) would be considered one 'of laughable tunes', then it shows holding a personal fear of death, probably while we are isolated on our islands not experiencing anything.
