A Place Called Home

When a person moves from one side of the globe to the other, sometimes it's just their physical self that migrates with them - but - what about their soul, their hopes, desires and dreams? Is it possible to fully detach yourself from a place your lineage has called home, a place you once called home and a place you have no wish but to call home? We often tell those that have migrated safely to this 'side' that they've made it now, that's they've come to the land of their dreams - but then why do we dream of the land we left behind both willingly and unwillingly, why do we feel so attached to a place we've barely known?
