Dreaming about ex – former husband or wife – is very common. It is a positive dream. The meaning of the dream is based on content. If the dream is an intense debate or fight then it is an indication that soon you will be facing arguments, accidents or fights. If the dream about ex is romantic or love then it means that you will be entering into a phase of life in which you will meet someone who will change your life forever.
Sometimes seeing ex in dream is also an indication that you are going to make some mistake in near future.
A dream to have a meaning it has to happen naturally and not due to any daytime incident influence. If you were thinking about your ex or talking about and then having a dream about the person has no value.
