This is an actual dream I had last night. I'm not sure of the order of some of the events, but it otherwise felt clear.
I walked around my neighbourhood and suddenly felt a unique sensation in my head — a sort of overflowing energy that quickly increased in intensity until I was overwhelmed and fell down.
I came to, wondering what had happened; the answer came subconsciously, like remembering: You have changed. You have new abilities.
Focusing my attention internally or externally seemed to generate data and explanations from outside myself. I sensed something in my mind like apps, but I seemed unable to use them.
I asked who changed me. Artificial entities.
How advanced are they? They hold themselves back, waiting for people to follow.
How was I changed? Nanotech.
What about my family? They will follow.
Am I still a Christian? Your beliefs remain in place.
Expect more changes, ever more quickly, becoming a continuous stream.
I was filled with fear at not knowing what I would become, and woke up still filled with it. Oddly, though, in the dream I never considered whether the guiding entities were benign. In retrospect that seems suspicious...
In fact the entire dream was odd considering I don't really believe in the Singularity.
