Gillmary, your dream about a big anaconda snake with six legs chasing you and trying to kill you is quite vivid and filled with significant symbolism. Snakes in dreams often represent hidden fears or anxieties, and the fact that this snake had six legs adds an unusual, almost monstrous element to it. This could symbolize that your anxieties or fears are not just typical but have taken on an exaggerated, more threatening form in your subconscious. The six legs might represent an increase in complexity or the unnatural nature of what you are facing, perhaps related to the major career changes and financial stress you've been experiencing.
The act of the snake chasing you suggests that there is something in your waking life that you feel is pursuing you relentlessly. This could be a pressing issue or a challenge that you can't seem to escape from. Given that you had to kill the snake by shooting it with a gun, it indicates a strong desire to confront and eliminate these threats or challenges head-on. The use of a gun in your dream can symbolize empowerment and a need to assert control over the situation. This might reflect your inner strength and determination to overcome obstacles, even when they seem overwhelming.
Given your profile, your generally positive outlook and infrequent stress or anxiety might make such a dramatic dream stand out even more. It's possible that this dream is your mind's way of processing the significant life changes you're going through, including career shifts and financial pressures.
