Dead People Are Alive

Dead: (1) no longer alive. (2) Lacking power to move, feel, or respond. (3) incapable of being stirred emotionally or intellectually

Alive: (1) still in existence, force, or operation. (2) marked by alertness, energy, or briskness. (3) still active in competition with a chance of victory.

To be dead is the opposite of being alive.
But isn't it possible that they're still alive?
Don't we have memories that are vivid and alive?
And don't we keep the memories of the dead alive?
So, through our memories, dead people are alive.
