A boa constrictor is not a venomous biting snake, instead it constricts its prey and swallows it. Biblically, snakes are often representative of wickedness or curses. They are usually symbolic of deception.
Positive: Dreaming of a boa constrictor could represent intelligence and wisdom. It could also symbolize God showing you wisdom or giving you new ways to get something done.
Negative: In a dream, a boa constrictor could represent generational curses are deception in your life. If a boa constrictor is wrapped around you or someone else, it could symbolize that the spiritual life is being sucked out of that person through deception or forms of wickedness.
