Seeing “someone trying rob”
in your dream

The bear symbolizes a powerful man, full of fortitude and wicked in his intentions, treacherous, and an evil-monger. It also alludes to an enemy, a foolish thief, an effeminate person, or one who robs pilgrims and attacks caravans. According to the legend, the bear used to be a woman and was metamorphosed. Dreaming of riding on a bear means one: 
(1) Will obtain a high position.  (2) Will experience fear, but be safe.

If a known thief robs someone of his money in a dream, it means that he slanders him. If it is an unknown old man in the dream, it means that a close friend will backbite him. A robbery in a dream also has positive connotations, except for a swaggerer who lives on betraying others. If one sees himself sneaking up to steal something in a dream, it means that thieves will burglarize his house or business. If one sees himself stealing something in a dream, it means that he will commit adultery or lie. (Also see Thief)
