What is there to fear? It will be just like living in this world now, only there are no consequences and you have more powers than even God could dream of (my spelling is even perfect in dream hehehe) If anything scary pops out at you, or you find yourslef in an uncomfortable situation in a LD, you can just woosh yourself or the thing away. There is so much fun and inner self to explore, dont let the notion of fear stop you.
