I suddenly realized that I still retained consciousness and could still think. This may be the feeling after death.I became a ghost, but there were no angels or demons to pick me up to heaven or hell.There is boundless darkness around.You can't see anything, you can't feel anything.I don’t know how long it took, but after countless attempts to explore the dark world around me failed, I finally accepted my fate, and I began to recall every bit of my life in the past twenty years.Regret spreads through my memories.
