I have varied dreams, but they always have a commonality: the subway (underground train). I could be in the tunnels, on the train etc.. Why?
Some of my dreams can be magical or mystical, while other can be quite normal but weird. I love dreaming and I keep quite good track of what I dream about. Why am I constantly (over 3 years) dreaming about the subway system in my city? Whether my dream merely takes place in the station or in the tunnels itself, I always end up dreaming of it! I don't want any annoying religious explanations so I'm categorizing this question as "Science". Thanks!
