Subject Ren, when I was researching dreams, I found out why my dreams were so vivid I could actually feel them, kind of. See, I found a bunch of sources that all said that some people dream so vividly, their dreamscape becomes a form of weak reality in which things can exist, and your sub-conscious mind moves itself there. Everything in the new dreamscape has some form of existance and can leave the dreamscape if it wants, but there's a form of size limit. This is sort of the reason why some things exist. Nothing from these "Created realities" Lasts forever in our world unless i was especially powerful. And Nightmares are always more powerful than dreams. So "Haunted houses." were once inhabited by people who could dream these "Realities." And their nightmares can leave their dreams and haunt them and it claims the house as it's own. The dreamer's subconscience is special. Once somethin from the dreamed reality leaves, it can't go back, it has to remain in our world until it either vanishes or dies off. But the dreamer's subconscience is different, it can leave the dream and enter another. While the subconscience is out, it's a form of "Astral projection." because you're in the real world, but yet not, because your subconscience does not belong there at the time. That was the black part the I said I walked through to get to my brother's dream. We have to sleep in the same room so there was so little space between us and it was pitch black. Once in another person's dream, however, they cannot leave unless that person is having the same kind of "Created Reality" dream. Your subconscience returns to your body once either you wake up, or the person your subconscience is invadin the dream of wakes up. It's very interesting.
