The snake in the hexagrams is a disaster, and of course killing the snake is a good omen. But the details in the hexagrams are that snakes are called dragons and pythons are dragons. In ancient times, there were dragons or white snakes, and emperors. But now the times have changed, I can only say that the middle and late life must be rich and expensive.
In addition, dreaming of the dead for more than a minute, according to your account alone, can't jump to conclusions.
I want to give some advice to the landlord:
First, be open-minded and realize that dreaming is caused by physical exhaustion or mental stress.
Second: I should be happy, because dreaming of killing a python is not something that ordinary people can dream of. For example, I never dreamed of killing a python in my life.
Third: Even if the body you dream of explains your omen, whether you dream of faking a corpse or bleeding, there is no problem. You can't fight with your wealth.
Finally, I wish you a little disaster, good deeds and great things.
