Snakes can have many different symbolic meanings in dreams, both positive and negative. The colors yellow and white are generally positive or benign, so a white and yellow snake is most likely a positive symbol such as regeneration, healing or insight.
The snake in this dream is a large problem with which the dreamer is struggling in real life.
Nothing
A "red snake" would have different significance to different dreamers. The meaning of the dream depends on the tone and feeling of the dream.
The snake is representing someone that you know in the real world.
From my own understanding, snake means someone doesnt like you.
See a psychologist.
First up, I dont mean to shock you, and interpretations mean absolutely nothing as long as you dont get obsessed by them. Second, you need to know, that for different cultures, a given color means different things. Eastern culture wise, It's possible that the black snake is your past that you are holding on to. If you are from a western society, black means death in the family . Yellow means purity when its on a snake. If theres black with yellow stripes on the snake it may mean the death of someone pure in your family. Such as a new born. But again, Id advise you not to take it too seriously.
In this particular dream, the snake probably is a symbol for something untrustworthy or repulsive. Seeing the ex-boyfriend with the snake, it suggests that those feelings are associated with him as well.
Look up Dream Book on Google. This tells what dreams mean. But, I know snakes are your enemies.
This dream has too many possibilities to suggest a single interpretation. The tone and feeling of the dream - peaceful, funny, threatening - are vital to determining meaning. Either the snake or the dog might be threatening or friendly. They might be threatening to each other OR to the dreamer. The colors of the snake and dog might be significant or irrelevant.
