Islamic Interpretation of Dreams (Ibn-i Sirin):

(Impudence; Shamelessness; Silliness; Stupidity) To make fool of oneself in a dream means ignorance.

To play silly before people in a dream means spiritual losses or foolishness. However, silliness in a dream is also interpreted to mean victory over one’s enemy, rising in station or expansion of one’s authority, ifhe is pretending.
