In my fantasy novel I have decided to have various flashbacks (not too many) too explain things about my characters and what made them who they are. I already have the flashbacks but I want to have various ways of cueing them. The ideas I came up with off the top of my head are: Waking up sweating from a dream of the past. Being reminded of the past from something happening presently. Explaining your past because of a question asked. I'm curious, what other ways can you think of to show a flashback?
