Another of my utterly strange dreams.
I and some friends decide to go out one night, and end up walking through downtown from our parking. Suddenly the sky and everything is blocked out with gray dingy fog. Down from out of the fog descends towers of stacked-up UFO-discs. Everyone panics and starts running in different directions, only to get "harvested" by the ships landing around us. But where I am everything is somewhat calm. I guess that once the ships fill and leave the tower so the next one up can come down, they need a clear space to leave, and I'm in the middle of one. Every time a ship takes off over me I want to panic and run, but every direction I turn is a ship on the ground, or one landing, so I stay where I am, and eventually the last ships have filled and they leave.
In the aftermath, with so many people missing and everything, life goes totally chaotic. We descend into a sort of Mad Max scavenger society while we wait for them to come back again. A year after they were first here, they come back and release everyone they'd taken, but none of them remembers the past year. Even more odd is that many of those taken now have exact twins, except that their twins are clear slates with no memories except that they are somehow connected with the originals. At first we don't know what to do about the "twins" but eventually we adopt them into our communities after we make sure they are actually human.
The still civilized survivors have built tall towers for housing as a defense against the lawless masses. We even build secret cubbies in them so we can hide deep inside the structures if and when the aliens come again.
Somehow in the dream I'm older, and I WAS a doctor, but I'd failed-out sometime before the invasion. I guess the chaos and disorder of a hospital ER setting had finally gotten to me and I had to retire early with my sanity nearly shattered.
Every so often the aliens stage another harvest, but they never take people they've taken before, which means that those of us who were lucky to have been missed get rarer and rarer.
Finally they catch up to me, even finding me and a few others in one of the cubbies of our building.
The aliens look remarkably like humans, but we guess they are using a disguise of some sort.
Being "harvested" is a bit scary, as part of it we are subjected to sprays that smell like super-glue. One of the things they do with the spray is glue our fingers together, and then glue them to our left ear so we can't struggle very much. Then they knock us out with another spray.
Before that, once they discover that I was a doctor they start to explain things to me a bit. They don't really intend us any harm, but they need our help for part of their reproduction cycle.
It turns out that they need us to act as surrogate mothers for their offspring. They surgically connect their offspring into our bloodstream through an external umbilical so we can provide the nutrients they need to mature. The process takes about a year, and our "offspring" absorb some of our knowledge as well.
Their offspring are always produced in pairs - exact twins, and sometimes this causes a strange sort of backlash, and the host-mother ends up producing an exact clone of themselves as well.
MY offspring turn out to be beautiful twin girls, who inherit all of my knowledge of medicine. I am awakened during their "birth" so I can be disconnected, and eventually returned to Earth, and that's the only time I get to see them.
I am finally returned to Earth, believing my group to be the last that they will harvest.
But then, just as my hermit-inside-a-tiny-community life is returning to normal, they come again. At first I want to hide in the cubby again, but I realize that they came for a purpose, and I can only imagine that the purpose is ME. So I convince everyone that this is what's happening and those who care about me prepare me to be taken and lead me up to the roof of the tower.
I'm greeted by the aliens who thank me for coming, and then begin processing me again.
That's when my cat awoke me for her breakfast. So I don't know any more.
Totally weird huh?
