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.
When you dream about snakes, chances are that the meaning of what you just dreamed about is related to challenging issues and feelings that you're facing in your daily life
From my own understanding, snake means someone doesnt like you.
See a psychologist.
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.
To see a snake or be bitten by one in your dream, signifies hidden fears and worries that are threatening you. Your dream may be alerting you to something in your waking life that you are not aware of or that has not yet surfaced. The snake may also be seen as phallic and thus symbolize dangerous and forbidden sexuality. The snake may also refer to a person around you who is callous, ruthless, and can't be trusted. As a positive symbol, snakes represent transformation, knowledge and wisdom. It is indicative of self-renewal and positive changes.
If that is what you have dreamed, don't worry about it. I can assure you, DON'T WORRY! nothing should happen.
From my understanding it means, that somebody hates you.
