@ShadowGhost23 one good way, at least for me, is to study history, culture, customs, and just generally of them. I have spent hours studying different histories to maybe include in my books, as to allow me to reflect a history similar to the real world's. If you do study go into with a fresh mind, don't try to think you know so much of templars or the slavs or the vikings (of which I will begin a self study of soon). Having those thoughts can kill imagination. Try this to assist: if you can everyday find a song of somekind. It can have any feeling you wish. Now focus really hard on a scene of a movie or show or a scene of something in the past, daydream it. If you can mantain that scene clearly and well, put yourself somewhere in it, and move around, interact and move to the flow of your song. Keep doing this, but dont follow normal history, change that which you know will happen (this is important). Allow yourself the ability of super strength, or you bring some people to another world which yoh create in your mind, or fly it is up to you. Keep practicing that. I do this for most of my writing but instead of me I put characters into scenes but it is hard to do if you dont have a strong imagination.
