PHSC, everything happens for a reason, and so there's a reason why Jacob told about his story... everything is connected the same way you are talking about connecting with those from "above" yet..
There's no difference btw psychological and physical, it's all the different expressions of the same energy structure of an higher self / soul aspect that is "trapped" or connected to the unified field / matrix / holographic structure.
So we can say it is different frequencies or expressions of the consciousness of the soul.
So in this matter I've also thought about that idea not only with those IS-BE's but also the ones that inhabited other planets and are also trapped in those systems, just like Harvey talked bout it.
Alexander talked about this.. The only difference here is he didn't use remote viewing, he use drumming ceremony that is used in shamanism, the sacred drum, wich the ancient people describe as a gateway for higher planes, it is what we call the footsteps of the sacred horse that lead us into the higher world.
The ceremony is almost the same for everyone in terms of it's connection with the spirit animal and the surroundings, although of course each one has it's own experience according to process of life that is dealing with.
In this case Alexander described his process that allow him to see the teachers daughter where she's on the other "side".
It is at the same time a message to her father but also for what you are asking, since there is no time and every reality is here and know happening.
So it is also a way to do what you proposed, in shamanic tradition this is like people came together to gather information for what ever they are trying to explore!
