Were the saints slain?
6:9 ...I saw under the altar the souls of those who had been slain because of the word of God and the testimony they had maintained.
So, you believe in “soul sleep?”
Is that what you are telling me?
Personally, I believe the Bible teaches that all who die in Christ Jesus are in the same situation as the Apostle Paul who said that he longed to depart and be with the Lord.
The passages in Revelation demonstrate that the dead in Christ are aware, in heaven, and with the Lord.
