You can drift off to where you are half asleep and not remember a single thing that had happened at that time. You usually don't feel your motions or think clearly or at all. It is common if you do...
In a way you can be dead but alive. You can be dead in the soul and heart--meaning having hate in your life, yet you are still living.
