My interpretation is that they lost someone very close to them and they are kind of in denial they feel like if they just keep looking they'll find the person eventually. In the end they do find the person but not where they had been looking they found them inside themselves. Their grief had blocked them from view even though they were always there "the night in my soul had been blacking you out". The all in my head represents their denial and their pain because the person who died wouldn't have wanted it.
