Imagine a scene. Fully inhabit it with all your senses, especially hearing and touch and taste. Close your eyes to put yourself there fully. Breathe deeply and count ten breaths. Slowly.
How does your character react? Goose pimples rise on his flesh in the cold night. The howl of the wind reminds him of an old friend’s voice. Is this scene soothing? Frightening? Sensual?
When you’re fully present in your scene, your character will feel it. And so will your readers.
