reincarnation is the process of being born as something else after you die, or coming back as something else after you die. Is really how I should have worded it.
also think about this, you know how babies cry when they're born. What if after we die we are immediately born as a new baby and the reason we're screaming is crying is because we want our old life back and we start to slowly lose our memories of our old life in our heart start to break because we loved that life but now we have to forget everything in order to live this new life
