Yes, we know that animals can be cloned since the 90s. To think this hasn't been carried over to human cloning in secret is a bit naive, just because they outlaw it doesn't mean it will be not done. Transferring consciousness I'm not too sure about. Maybe it could be done from using the tech of a more advanced society that knows how to do it, but we don't even know how to create or explain precisely how consciousness can manifest in science, but we are getting there eventually with neuroscience. I don't necessarily accept all the claims of DM, but they are interesting to hear about.
