Spiderman dream may represent an unusual degree of courage or nerve as you attempt to make someone arrogant embarrass themselves. Risking everything to pressure someone into doing the right thing for themselves.
Example: A man dreamed of seeing spiderman. In waking life he was risking his relationship with his elderly father by complaining to city building inspectors about his father’s neglected property. He hoped his father would go broke trying to comply with the city orders and be forced into selling so he’d retire and stop living in a home that was falling apart.
