I think the intuition here is: - Being surrounded by people one cannot connect with, increases the feeling that one is socially isolated and an 'outsider'. They are unable to engage with their organic natural (social) environment - Whilst being in 'a forest alone', offers the person a chance to engage with their natural environment and more easily connect with it, just by being there. You don't have to do anything but just exist in it. In a way you are accepted and do belong to that environment (genetically/instinctively). So it acts to counter feelings of 'not fitting in'.
