MrRING - I hope you'll not give up on this if it's something you truly want to do. (As long as you can keep far away from angry dark shapes.) You know, sometimes these things can take a long time. Sorry if I contributed to the apparent, (hopefully temporary), demise of this thread. Although, it appears that I did as I'm one of the last to post anything here before all conversation stopped over a month ago.
I've now read the whole thread, and have a couple of thoughts which may, or may not be helpful. First, I was surprised when I read that in your first attempt you and your friends all dreamed that you were lost, and being pursued by an angry dark shape. Surprised that after that you'd want to try it again, and surprised that you and your friends got anywhere at all by simply thinking about it.
I've never heard of anyone, (other than you), doing this by simply wishing it. That may be where you're having trouble; trying to do it again the same way. It may have been a once in a million thing. Other than these things happening completely spontaneously, without any effort, or even conscious desire to do so, I would think that some effort has to be put into it. I can only think of two ways. One is to ask a higher power to do it for you. Two, is to use some technique, like remote viewing. The higher power request appears easy at first, but consider how long a serious faith might take to develop, and the target remote viewing technique I know is difficult, and tedious. It's just hard work, at least for a sometimes very lazy person like me. Real time and effort is required either way.
Also, as I mentioned before, I really think different rules apply to different states of consciousness, and when you don't adhere to those rules you don't get the desired outcome. For instance I don't think you can visit a real place in a dream. I believe that dreams are a creation of the dreamer, or dreamers, although real people can move in and out of them. So trying to meet up with people at a real world location while dreaming is going to produce something else altogether. In targeted remote viewing you visit real places, while awake, but they may appear unreal because so much of the place will be represented symbolically instead of literally. In extended remote viewing you visit real places that are completely literal, while asleep, but you are not dreaming, you are having an out of body experience.
So, you may want to give something entirely different a try. I imagine there are at least a few, if not many, other techniques out there as well. If you do want to realize your goal though, I think you may need to employ one of them. Good luck to you.
