Psychologically: He somebody wants to come along in the dream if he has to laugh in reality nothing. Dreams of 'fun and Tollerei' are more suppressed signals (and from informal / professional sphere more limited) joy of living. One knows that one comes along 'to the fool' if one is to want to have more fun in own life. So one tears himself together and puts on as expected his most serious face. 'Of all mask!' then the subconsciousness shines in the dream - and warns about other abnegation and resignation.
