Interpretation 2 — Martha Clarke

This does not have to be a prophetic dream. It may be warning of a situation of neglect or abandonment on the part of your partner. Although it sometimes signifies that you should learn to develop yourself alone and be more independent.

Seeing yourself as a widow or a widower announces moments of suffering by gossip that originates in the environment and could create enemies with third parties. You should try to discover who is trying to cause you harm so that your relationships with others are not harmed.
