This is why André Malraux said that man is not what he thinks he is, he is what he hides. So we have the anxiety to communicate and express ourselves to others, because we can only know and picture ourselves in society in relation to others. So that artists are people driven by the tension between the desire to communicate and the desire to hide according to D.W. Winnicott.
“A creature that hides and “withdraws into its shell,” is preparing a “way out.” This is true of the entire scale of metaphors, from the resurrection of a man in his grave, to the sudden outburst of one who has long been silent. If we remain at the heart of the image under consideration, we have the impression that, by staying in the motionlessness of its shell, the creature is preparing temporal explosions, not to say whirlwinds, of being.” ― Gaston Bachelard, The Poetics of Space
