Dreams in my opinion can tell many things, wether an important person who is deceased in your life is coming to tell you their okay or how a situation you’ve been going through we’ll be planned out. Some can mean nothing and those are the dreams we tend to forget. Others we forget and the remember when their needed most.
I think they are wrong. Many dreams are meaningless - just based on our experiences during the day. For example, after spending the day reading scary stories, you could have a terrible nightmare. This dream doesn't mean anything; it is just a result of you reading those stories.
