I am a born again Christian and I can tell you that so many of us, all over the world, are getting the message from the Lord God: "prepare to stand before me on a moment's notice. The storm that is coming is so severe that many will perish. Tell others to repent and get saved now, for soon it will be too late for many".
That sounds to me, in many ways, like all of God's people are supposed to prepare to depart for eternity as well.
Your dream falls in line with all these prophesies.
But here is the point: everyone will die sooner or later. The victims of El Paso did not plan to depart yet.
If you die for whatever reason, if you are in Christ, you will be taken to heaven. So there is no reason to fear death anymore. Watch YouTube videos of people that have seen that place.
If you are having these dreams about death all the time, and you are no saved, what are you waiting for?
Don't take tomorrow for granted. Repent of your sins and get right with God asap.
How to accept Jesus Christ as your personal Savior and Lord?
It is the easiest thing in the world. Just close your eyes, focus on him and pray something like this:
"Lord Jesus, I repent of all my sins and I ask you to wash me clean. I am sorry for all the bad things I have done and the many times I broke God's Will. Please forgive me and fill me with the gift of the Holy Spirit. I want to belong to God. I want to be adopted into his family as his child. Come into my heart. I give you control over my life. Please lead me through the Holy Spirit and make your Word real to me. Fill my soul with the peace that surpasses understanding and help me change so that I may lead a life that is pleasing to you. I want to go to heaven and I want to be called by the Fathers name. As of today I declare that I belong to you". Amen
