Last night, I had a dream. I don't know if it was because I read your post here or if I was given some discernment about possible events to come. I'm still praying about what this could mean so bear with me.

Some info before I post my dream...recall the very first "Passover". Moses instructed God's people to put lamb's blood on their doorpost so when the Angel of the Lord flew over and saw the blood, that family would escape God's judgement. All those without the lamb's blood would suffer God's judgement through the death of their firstborn.

Also (this may seem unrelated but bear with me for a minute), recall in Genesis 6 that the fallen angels mated with the human women and had children by them. Many scholars believe this is why God sent Noah's Flood, to eradicate these offspring/human-angel hybrids.

I believe there are many "offspring" roaming the earth today, from possible sinister "reptilian shapeshifters" to more benign RH- blood types who exhibit no other outward traits (I include the neg. blood types because I cannot understand why God would create someone of this blood type who would spontaneously abort a child they are carrying of positive blood type without receiving a shot of Rhogam. The only other species on earth that spontaneously abort it's unborn is a donkey because it is a HYBRID of a horse and mule. Makes you wonder if those with RH- blood are also hybrids. HMMMM...)

Now to the dream: April 18th is the start of "Passover" (according to the OP's link, the 18th is Passover beginning on the evening of the 17th...but when you google date for Passover, it says it is the 19th, beginning the evening of the 18th. Might want to double check that for your own satisfaction). In this dream, on the evening of Passover, the Angel of the Lord flew over the world again. This time He was looking not for the lamb's blood on the doorpost but for those washed in the Blood of the True Lamb, Jesus Christ/YahuShua Ha Mashiach. Evidence of their true conversion to YahuShua as their Savior was visible to the Angel of the Lord through the light of the Holy Spirit who dwelt within those "washed" in the Savior's Blood. These people escaped God's judgement.

Those who did not possess God's Holy Spirit by belief in His Only Son awoke to a much different reality than the one they knew before this latest Passover of the Angel. In this dream, instead of the deaths of all the firstborn, the Angel of the Lord lifted the "veil" and those who are not saved by the Blood of the Lamb saw themselves for who they really are. Most did not recognize themselves in the mirror and became frightened. Several expressed this fear through violence and aggression. The cities were no place to be.

In the dream, I recalled thinking that this must be the end of the "Age of Grace" where ALL appeared human and all were given the same chance to come to the Father through belief in His Only Son. Now, those who had chosen not to believe were more susceptible to the coming deception that "aliens" created life on this planet (they will believe this because it will explain why they suddenly look the way they do). Then those who still appear human (in the image of God) will become the targets because we did not "evolve"...do you see where I am going with all of this?

This may have just been a dream...or a forewarning. Maybe the OP is on to something. I did not get the sense from the dream that believers were raptured at this point, only that the Angel of the Lord will once more "Passover" the world. The results this time, however, will make it a time unlike any other! Civil unrest will be an understatement and I believe the governments of the world are preparing for just this scenario.

Make sure you know beyond a shadow of a doubt that you possess God's Holy Spirit through belief in His Only Son! There will be no mercy without repentance. If you have not done so, humble yourself, repent of your sins and ask Jesus to be your only Savior. If this wasn't just a dream but a forewarning, your faith and His protection will be your only hope!

May God be with us all!
