Perhaps they were dead and imagined they were living? Perhaps everyone was dead? Perhaps he’d always been dead? That what he’d always assumed was life was actually death?

But it struck him that people are not really dead until they are felt to be dead. As long as there is some misunderstanding about them, they possess a sort of immortality.

Some people live as though they are already dead. There are people moving around us who are consumed by their past, terrified of their future, and stuck in their anger and jealousy. They are not alive; they are just walking corpses.

Remember, when you are dead, you do not know you are dead. It is only painful for others.
The same applies when you are stupid.

Many of us live like dead people because we live without awareness. We carry our dead bodies with us and circulate throughout the world. We are pulled into the past or we are pulled forward into the future or we are caught by our projects or our despair and anger. We are not truly alive; we are not inhabited by awareness of the miracle of being alive.

Intelligent and thinking people began to wonder why the Lord would resurrect the dead, if they were either in heaven or hell, and their portion forever unalterably fixed. Then they began to wonder why the dead were called dead, if really alive. Then they wondered why our Lord and the apostles said nothing about the dead being still alive, but on the contrary always pointed to a resurrection as the only hope; even declaring that if there be no resurrection all have "perished". (I Cor. 15:13-18.) Then our Lord's words, promising an awakening to "all that are in their graves," began to have a meaning; and it gradually came to be seen that the dead are not alive, but that death signifies the opposite of life. And those who sought found that the Scriptures are in perfect harmony with themselves on this subject, but in direct opposition to the common traditions of to-day, received from Papacy.</br>The root of error being thus removed, the various branches soon began to wither; and soon it was seen that instead of everlasting life (in misery) being the punishment of the wicked, the reverse is the Bible statement of God's plan ;- that everlasting life is the reward for righteousness and that death, a cutting off from life, is the punishment for wilful sinners.

When you are dead, you don't know that you are dead. It's pain only for others. It's the same thing when you are stupid.

… Mr. Og. most humans, in varying degrees, are already dead. In one way or another they’ve lost their dreams, their ambitions, their desire for a better life. They have surrendered their fight for self esteem and they have compromised their great potential. They’ve settled for a life of mediocrity, days of despair and nights of tears. There are no more than living deaths confined to cemeteries of their choice. Yet they need not remain in that state. They can be resurrected from their sorry condition. They can each perform the greatest miracle in the world. They can each come back from the dead…

In every way that counted, I was dead. Inside somewhere maybe I was screaming and weeping and howling like an animal, but that was another person deep inside, another person who had no access to the lips and face and mouth and head, so on the surface I just shrugged and smile and kept moving. If I could have physically passed away, just let it all go, like that, without doing anything, stepped out of life as easily as walking through a door I would have done. But I was going to sleep at night and waking in the morning, disappointed to be there and resigned to existence.

And how can the dead be truly dead when they still live in the souls of those who are left behind?

They say I have died I still felt alive I won’t believe their lies…

This was in truth not living; it was scarcely even existing, and they felt that it was too little for the price they paid. They were willing to work all the time; and when people did their best, ought they not to be able to keep alive?

Unbeing dead isn't being alive.

How surely are the dead beyond death. Death is what the living carry with them. A state of dread, like some uncanny foretaste of a bitter memory. But the dead do not remember and nothingness is not a curse. Far from it.
