Ever had a dream that didn't appear to be visually or aurally scary, but inside about you felt as if you were undergoing a poltergeists frightening and hellish prank?

I've learnt that dreams can sometimes greatly augment human emotions to the point where they are more abstract than waking emotions. With this, I have had some dreams where the visuals and events aren't always that horrific, but during and after the dream, I feel this very frightening and demonic, hellish emotion within me; like I was imposed a sample of what emotions are like in hell, without always being exposed to terrible dream scenes.

What's up with that? As Swedenborg said, dreams come from both heavenly and hellish beings, so that's one thing I'm considering... I'm not even religious but I believe that.
