Hi. I'm eclipse. 😀 those dreams seem to be pretty involved. Also not like usual dreams I hear of. you mentioned some tech that might exsist. A med bed is the biggest thing. also yeah they can use cubes or maybe even spheres. in a way I feel crystal like stone can even hold information like a compact disc. They can most likely conduct energy to. Especially a metal spheres.i personally think you should be open about your experiences because they are most likey not coincidence. remember how In total recall the guy dreamed of a lady friend/fellow spy and it turns out t to be a memory? I can't judge because I might have been a German citizen and married. yet it wasn't a dream. It was a intuition that I can say might be my imagination. however I'm not so sure about that. Anyway cool post.
