Psychologically: Idiot often means that one acts out of proportion and runs the risk, therefore to suffer failures and losses. Then one must recognise from the living conditions what this refers specifically to. Also: An exclusion symbol, the 'idiot' is different than the others, they do not understand him - he does not understand them. Moreover: Symbol for the (edged out) wish for a childishly carefree, easy life in which other the responsibility can carry and one itself allow to do. A dream signal if somebody is completely demanded too much spiritually / professionally and is not able 'simply any more'. Popular: (arab).: luck in the play. (European ones).: unexpected pieces of luck expect to one.
