To dream of anaconda represents feelings of being powerlessly restricted. It may also reflect your own attempts to guarantee that someone else is totally cut off from their goals. The threat of failure by being slowly restricted. Feelings about relationships or business dealing being gradually “strangled” or “suffocated” by problems.
Example: A woman dreamed of having to kill an anaconda snake. In waking life she had to fight against someone who was making comments about her business which was causing her to gradually lose a lot of money.
