The Island symbolizes helter, security and freedom. If our island is sinister and uninhabited that reflects the despair and helplessness of our timidity. If we take refuge on an island fleeing from our enemies, then that reflects the desire to escape from our current conditions. If the island has many people on it, then it means that in real life we feel alone and we fight to find new friends and companions.
