A net can mean different things in various aspects in life. On the social aspect, a net means you might be entangled in some complications with people. Some scammers may have cooked up elaborate schemes to ensnare you in their net.
Dreaming of seeing a net can mean you are caught in money problems. Cash and assets are the main preoccupation of greedy people. If you have reason to believe you are embroiled in a money trap, try to leave, or seek help from different quarters to distance yourself.
