What do you remember hearing in that moment? Think about the background noise as well as what was said.
What do you remember smelling in that moment?
What do you remember seeing in that moment?
What do you remember tasting in that moment?
What do you remember feeling (as in touching) in that moment? Go ahead and approach this from an emotional stand point as well. Think about others' emotions in the scene as well as yours. Remember that people rarely experience just one emotion at a time.
Don't feel like you have to answer all of the sense questions (our memories may not collect everything), but try to. You might be surprised at what you remember. There's no need to use all the details created by this exercise in the actual scene, but they'll help you retell it in a livelier way that readers will appreciate.
Fiction writers can use this as well to perk up the scenes that fall flat or to change those "tell" moments into "show" ones. Experience the scene through your characters' or narrator's eyes and answer the questions. Rewrite the scenes with your sensory notes and see what a difference it can make.
