Metaphysics is parts of the universe which go beyond our  understanding of the universe which we can not observe. It’s also a theory with no real evidence in and can not be proven by science. In in Shakespeares Macbeth the witches are an example Metaphysical creatures. In act 1 scene 1 the witches predicted the future about Macbeth being thane of cawdor and king. ‘ All hail, Macbeth, hail to thee, thane of Cawdor!’ and ‘All hail, Macbeth, thou shalt be king hereafter!’ this is Metaphysical because nothing in which our science understands can predict the future.
