Do dreams appear opposite in Interpretation?

• Hey guys, I just remembered and incident that which happened years back, my uncle dreamt of buying a new car. But when he discussed the dream with a man who claim to be a dream interpreter, he said the car signifies coffin, and that it means he's going to die. I made up my mind not to share my dream with anyone. I don't know, but do dreams appear opposite in interpretation?
