I had a super weird experience with this. I had a dream that ACTUALLY BECAME a series on Netflix shortly afterward.
In my dream, my dad came to my family and told us he heard about this great rejuvenation procedure which was supposed to make you feel young again and solve all your medical problems. So he went into this facility where we were supposed to go pick him up at night. But he called us and said something went very wrong and we needed to pick him up in the back of the building. For some reason, we picked him up in a box truck, like a small moving truck.
When we got there, we found him and another old guy, looking nearly dead and drained. We put them in the back of the truck and I rode with him and talked to him about what happened in the procedure. While we were having this conversation, the other old guy died. He told me at some point he realized they were going to let him die and he ran away and called us. The rejuvenation procedure was actually a cloning process and now there was a clone of my dad out there, only younger and healthier, and the clone was going to take over living my dad’s life.
That’s about where the dream ended, and I woke up thinking that was a great premise for a Sci-fi movie. Then about a month later, this Paul Rudd series came out on Netflix called “Living with Yourself” with almost the EXACT SAME PLOT. I am still creeped out by the whole thing.
