A skull is a symbol which in “Hamlet” by Shakespeare symbolizes nothingness, illusion, death, as well as obsession on the ideological grounds; adherence to the illusory ideologies, derived both from nature, experience, and metaphysics, so from dead ideologies. In a positive meaning, it occurs rarely, and symbolizes the strength of mind, because the skull protects the brain. The circumstances in which the skull appears in a dream will allow to choose the right meaning of this symbol.
