This song deals with depression and how it can sometimes overcome us; how sometimes we need to numb ourselves in order to feel at home. In Aurora’s words:

It’s not a good way of living, making yourself numb, trying to let every day pass by as quickly as possible. But at least it makes us happy for a while. We are home."

Even though by numbing ourselves we can feel ‘warm’ for a little while, there is no way one can live like this; this is only surviving, nothing more.
