The adrenochrome thing is deception. Don't fall for it! There is some truth behind it though. As you are about to die your body starts to produce something that ought to make it able to connect with the (I don't know how to describe it) after-life world, to "download" all your memories and your soul. It is mainly designed to protect you from temporary problems. All babies are born with this thing in their blood, to protect them from the oxigen-deprivation at birth. Humans are producing this thing if they are terrified. And childer are terrified very easily. So they are torturing children and then take their blood. Why? Because they want to take over this after-life world. This other world is god itself. And they found a way to connect to it consciously. There is no time and space as here, so they have access to the past and to the future. But they can't change anything - yet....
