What does it mean to see a big snake in a dream?

yea in my dream

i dreamt about

a snake that i raised and i loved so dearly

and the snake started talking to me outa nowher

and was saying all these bad things like cursing me and all

giving me bad ideas, and it got to the point where it wanted to kill my dad

i then opened the front door and told the snake to get out

and i cried so much wen it left

that was in ma dream
