Dreamtime - The communication with your dad sounds like the real thing. People do take courses after they die and in doing so go through growth spurts.
The children and the lightning, well, it get the impression that you have a caring nature for children, and in fact your dream shows you sharing their inner life- the swimming pool. It seems that, with the mention of intuition, I think that the storm shows you having an intuition that a sudden change is about to happen, probably brought about by a major change in the lives of some people, But you are instrumental in dealing with the emergency. Of course it may be an internal rapid change that you face.
By the way, if you wanted to check were I get the information from - courses when your dead - ask me.
