Which facts exactly do you rely on? In Isaiah 14 there is a long passage about the king of Babylon dying, and according to many the dead know nothing. They are supposedly annihilated, destroyed, gone! God, Himself, speaking, these dead people in שאול/sheol, know something, they move, meet the dead coming to sheol, stir up, raise up, speak and say, etc.
Isa 14:9-11 (KJV)
9) Hell [שאול] from beneath is moved for thee to meet thee at thy coming: it stirreth up the dead for thee, even all the chief ones of the earth; it hath raised up from their thrones all the kings of the nations.
10) All they shall speak and say unto thee, Art thou also become weak as we? art thou become like unto us?
11) Thy pomp is brought down to the grave, [שאול] and the noise of thy viols: the worm is spread under thee, and the worms cover thee.

22) For I will rise up against them, saith the LORD of hosts, and cut off from Babylon the name, and remnant, and son, and nephew, saith the LORD.
In this passage God, himself is speaking, and I see a whole lot of shaking going on, moving, rising up, and speaking in . These dead people seem to know something, about something. We know that verses 11 through 14 describe actual historical events, the death of Nebuchadnezzar, king of Babble-on.
Here is another passage where God himself is speaking and people who are dead in sheol, speaking, being ashamed, comforted, etc.
Ezek 32:18-22, 30-31 (KJV)
18) Son of man, [Ezekiel] wail for the multitude of Egypt, and cast them down, even her, and the daughters of the famous nations, unto the nether parts of the earth, with them that go down into the pit.
19) Whom dost thou pass in beauty? go down, and be thou laid with the uncircumcised.
20) They shall fall in the midst of them that are slain by the sword: she is delivered to the sword: draw her and all her multitudes.
21) The strong among the mighty shall speak to him out of the midst of hell [שאול] with them that help him: they are gone down, they lie uncircumcised, slain by the sword.
22) Asshur is there and all her company: his graves are about him: all of them slain, fallen by the sword::[ . . . ]
Eze 32:30-31
(30) There be the princes of the north, all of them, and all the Zidonians, which are gone down with the slain; with their terror they are ashamed of their might; and they lie uncircumcised with them that be slain by the sword, and bear their shame with them that go down to the pit.
(31)Pharaoh shall see them, and shall be comforted over all his multitude, even Pharaoh and all his army slain by the sword, saith the Lord GOD.
That is simply not true.
That is superstition and traditions of men, not biblical.
I quoted scripture that makes it biblical, and very true. God himself is speaking in both passages!
