Death can be a rewarding experience spiritually. You are given many peices of your personal puzzle and many questions raised on your life journey are answered.
My death experience was different from most, but then again I was way younger than most when it happened. It took me years to figure out what it meant and then only through dreams and other communications.
Spiritual people can sense the presence of other spiritual people and a truly spiritual person respects the faith of others (as opposed to trying to convert them) because a truly spiritual person realizes that we are all on separate journeys through our life experience. No matter what our faith we take this journey as individuals.
