I dreamed that my wife was electrocuted last night, and I cried! What do you mean?
Death, in dreams, refers not to real death, but to the coming of change. You may find that your wife has changed recently, such as habits and personality changes. Any change may trigger you to have such a dream.
You cry to show that you love your wife deeply. For example, you are worried that she will leave you. This is a sign of love. Crying is still the negative pressure accumulated in the heart during the day, and it is vented through crying in dreams.
