Apart from seeing the actors say that they feel the Force and seeing them use it. I've always felt like since we aren't actually there in the scene, in the fiction, that we have a difficult time actually understanding how the characters actually feel the Force. Like in Episode VI, Vader tells Luke that "its impossible to resist my son.", but since I never could feel what Luke was feeling, its difficult to understand what the Emperor might be doing through the Force directed towards Luke. I wonder how it feels to use it, does one get euphoria, or a sense of bliss, or when someone uses the Dark Side. I wonder how that feels. "Feel the Force around you." Yoda told Luke, but how does it feel? Is it ever explained?
