How to address the feeling, when you are among the number of people and things, but somehow detached from anything else. Lost in your own personal world. In a mysterious state of isolation among so many other human beings. Out of place, not in harmony with the outer habitat. Passers-by are not even noticeable, they become a background, not much different from concrete and glass. Each person has this personal space, unique atmosphere around, their inner world. Everybody in the crowd is unlike anybody else and the gulf between each person is gapingly wide. What is there and cannot be seen but felt is the thoughts, emotions, vulnerability, fears.
