Are they okay? What is going through their mind? Are they frozen in time? Are they not thinking at all? Are they not feeling anything? It may look odd sometimes because it can happen at any moment, staring into nothing. Even during a conversation everything can stop. It’s not a conscious thing and people themselves are not always aware this is happening. I know now that it’s a natural coping mechanism and the mind gives us a welcome rest from emotional stuff. It’s okay to stare into nothing.
