Psychologically: Who dreams of it, has itself in a kind typical for him 'overeat' - these can have been too plentiful (and too substantial) sensuous pleasures, but one can also feel a Übersättigung by impressions, charms etc. One does not want to be to blame himself 'for it' and pushes it other in the shoes that one 'oversaturates' himself now - and feels not especially well: fattened just. Popular: (arab).: one cannot force a luck.
