I have a strong depersonalization and I thought that we live in some kind of simulation, in virtual reality.
I had about such a crazy idea: I assumed that there was some kind of network (like the Internet) and everything around (including people) is part of it, like websites on the Internet. Something that is called human consciousness is a computer program, 0 and 1, it connects from this network to self-replicating drones (human bodies). I also assumed that the most valuable thing in a human being, what is unique for everyone, is his memory, experience, and it is stored in this network, synchronizes with the "cloud" when people sleep (does sleep somehow affect memory?). I thought that the whole world is of a digital nature, that the fundamental basis is information.
