First of all, my understanding of dreams is often the opposite of what I dream.
Graveyard: Dreaming of a graveyard is a bad thing, which indicates that bad news is coming from a distance.
Wading: It is related to love and friendship. If the water is crystal clear, it means happiness; if the water is turbid, it means trouble.
Snake: From a psychological point of view, dreaming of a snake is a bad sign. You may be deceived by someone you trust very much, or misled by friends or colleagues. I think you will experience something you can't believe.

I'm worried that you will suffer setbacks in your life because of the above signs in your dreams. I suggest you take precautions!
