I'm curious what you mean by this. Are believer who have died, unconscious? Are they unaware of anything? Are they in limbo until the end?
Biblical term Peter used in the scripture. They have died and the body and soul separated. For the believer the soul and living spirit are seperated from the body.
If you believe in a resurrection whether pre-trib, mid-trib post -trib or as the amil the body will come to life is a resurrection form and thus be awakened from the sleep of death.
