it honestly depends on your frame of mind... If you already have a realationship with jesus and you know him in your heart, then the effect definately feels like heaven (nirvana), nothing but peace and love. However if you have not accepted jesus as your personal saviour, then it's more like fear. If you are a worshipper of demons then it will have a negative affect on you and surely you could die.

The spirit is fealt slightly at concerts and stuff... when the rockers are all doped up and singing with all their passion. The croud surely can feel the effects. Much like Elvis, he had some spirit in him.
