Now in the second year of the reign of Nebuchadnezzar, Nebuchadnezzar had dreams; and his spirit was troubled and his sleep left him.
Dreams from God occur much the same, except this time He wants to tell us something, or show us something that perhaps our conscious minds have trouble comprehending. I often dream of trying to help people that can't or refused to be helped. In my awake state, I can't imagine people wanting to say, "No", to God and His ways. But, they do. I keep trying to help. Then, my dream will be trying to save someone who has their doors locked from the inside. When I try to get them out, I get hurt because they have purposely put a trap on the inside of the doors, and windows, so that the trap goes off when I try to get them out. At other times I will dream of me doing something that I can't see myself doing in real life. Then, when I wake up I can believe it is possible, because I saw myself doing it in the dream.
Like the above dream, some are easy to interpret, others are much harder to figure out. A good book that has been helpful to me is called, "Understanding the Dreams You Dream" by Ira Milligan, https://images.search.yahoo.com/yhs/search?p=Understanding+the+Dreams+You+Dreams+Ira+Milligan&fr=yhs-Lkry-SF01&hspart=Lkry&hsimp=yhs-SF01&imgurl=https%3A%2F%2Fimages.gr-assets.com%2Fbooks%2F1430097233l%2F230000.jpg#id=-1&iurl=https%3A%2F%2Fimages.gr-assets.com%2Fbooks%2F1430097233l%2F230000.jpg&action=click.
