i believe that reincarnation is not possible. i believe that after death, humans will be questioned in their graves. based on their life, they will either be punished and tortured, and their stay will be made as uncomfortable as possible, or their graves will expand and be like a foretaste of heaven, and anything in between. if they get punished, their stay in the grave will feel like eternity untill the day of judgement, and if they have a comfortable stay it will feel like less than a day untill the day of judgement.
