More information about this particular dream and the specific behavior of the snake would be needed for a reliable interpretation. Generally speaking, dreams of poisonous snakes suggest the dreamer's fear of some unspecified threat. In this case, because the boemslung (Boomslang) is a tree snake, the dreamer might fear some attack from "above," perhaps from supervisors or "higher ups."
... The image of the boomslang might have been drawn from the Harry Potter movies, in which the shed skin is an ingredient in Polyjuice Potion, or from the Marvel Comics' supervillain, Boomslang.
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.
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.
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.
It probably means that you have an interest in gambling.
Without additional information about the setting and actions in the dream, it is impossible to give a reliable interpretation. In general, a hairy snake of any color is most likely a phallic symbol.
its just a dream it dosent mean aneything
