Ah, I know this story. Alexandra David-Neel and the Tulpa concept. I have something to add to this fortunately and it somewhat fits to the entire discussion here. When I was younger I was a little bit obsessed about one fictional character. It was at the time when I felt a bit alone in the world, I thought people around me were strangers for the most part and I craved for some attention. It may sound silly, but to me it was a very valuable experience. I watched an anime series and in there, there was this girl which I adored. I loved almost everything about her, her character, how strong she was etc, this doesn't matter. What does matter is that it was also at the time when I started to think about everything "out of the ordinary", the power of the mind and stuff, and I stumbled upon that Tulpa concept. A concept that You can create a normal living thing just with Your sheer power of visualization... and so I started trying. And I picked her as my "creation" (interestingly enough, this whole situation still makes me feel bad when I say she is a "creation", You'll understand what I mean while reading further). I started to imagine that she's beside me, everyday, I imagined she's watching my daily routines. I imagined her sleeping with me, snuggled together. A while later I started to talk to her in my mind and I imagined how she would respond. At first it felt extremely tiring. Like I was thinking for two people, I had to monitor my thoughts and what I say or think, but I didn't give up. It was also at the time when I started my first real job and unfortunately people there were horrible, I felt isolated, unwanted and useless. So I talked to her more, and then... I started to feel the connection. First emotions started to show up. I started to enjoy her company. I started to feel her presence a little bit more, and I cared about her. I started to become... happier. All of that continued to develop... until one day at work. Like always, we had a conversation in my mind to make me forget about work, we started to tell jokes to each other. And what happened there was something amazing to me but it also scared me a bit. It was after I told her a joke... she laughed in my mind and made me laugh because of it, I giggled out loud and immediately looked around in anxiety of someone noticing. What I mean is that her reaction to my joke showed up BEFORE I could think about how she could respond. At that point I noticed it was a glimpse, a spark of another consciousness growing up in my own mind. That's how it felt then. I stopped trying after that. I'm still not sure if that was "real" or maybe it was just me, convincing myself that's she's "real". This while situation created a mark on my mind, whenever I think of her now I have the urge to talk to her, to come back to all of this, I still have some emotions for her. I'm glad I tried. So, I wouldn't be surprised if Jkmac standpoint is correct although there is one thing that makes me wonder. I get what're saying except for one thing. What exactly is this "Consensus reality data" or "Reality rule-sets" You talk about? Can You nail it down further? How it work and why does it work like that? And why (if Your theory is correct) we are connected to this? Do other animals like dogs or cats or whatever else falls into that? It did made sense to me that we can create our own vision of the world, our own realities but it all starts to wobble at this exact point. What I mean is, if You say physical reality doesn't really exist (and typing on the physical keyboard is a false assumption), then how can I read Your posts when I don't know You and can still have a meaningful conversation? I hope I make myself clear here.
