I read an article that speculates that dreams are our mind's way of training our body on how to react should we get into a life or death situation. In the times of the early man, they were surrounded by animals that could kill them all the time. They learned from experience how to avoid them , but also while they were asleep their minds played scenarios in their dreams to train them while asleep. Is that why most of my dreams involve me running from some unknown danger? So if that should ever happen, some part of my mind would know what to do? What do you all think?
