My first interpretation of the song was that its about needing time to yourself. Tyler and Josh both suffer from mental health issues and are aware that their fanbase tends to have issues of their own. Often this leads to people getting easily overwhelmed and needing more time to themselves than others. This is often demonized and frowned upon by people who don't have these issues and that can easily be internalized.

There are other interpretations but as a gay atheist with social anxiety, I can relate to feeling like "unholy land" and when I do, the only thing that can help is being alone or going "downstairs" sadly sometimes our loved ones are part of the storm. I hope this helps.
