Thanks for taking the time to share your experiences there Karla.
So this is an area I know a lot about and I am wondering from which direction I should approach this first.
This is what I sense: Based on our time period right now, in connection to the astrological ages and cycles, which do fit into the Mayan long count calendar for another reference, the belief system and vibrational space the Earth resides in, makes it more difficult for some abilities to be used. So it's not so much about knowing how to do something and doing it, but that there is a limit on what can be done be accomplished at this time and in previous years.
Through many of my own past life regression clients (with the method QHHT) I have seen examples of their interactions down here on Earth, which are temporary, and they form a physical type of body for that temporary experience to accomplish their mission. This is one area of 'proof' for me.
So I mentioned
Invisible Helpers by Charles Webster Leadbeater, which is a great and easy book to great that talks about this topic. But this is more focused on incarnated souls of course, however, the same principals apply.
People may wonder why this doesn't occur more frequenty, as in strange occurances in life that would be reported on film, in the media or alternative media, and so on, well, like I mentioned first, it's harder to do right now I feel, because of the time period and cycle we are in, but it will become a lot easier again, like it once was.
The other factor here is that the Earth is just one place, one plane, one realm, where when you finish a life here, you have other tasks to accomplish and other things to do as part of the process of soul growth, so unless there was some role / position, where you would permanently reside until you accomplished a certain goal that directly related with Earth, there would be no need to come down here and manifest.
Those who have passed over and want to visit their loved ones, won't immediately be able to do this, to manifest in the physical, unless they had a lifetime down here of mastering astral projection and the skills involved with materialising an etheric based physical form; but even then, to master astral projection and out of body travel, you would also be gaining an expanded level of spiritual and consciousness progression. And what this means is that your motivation to do such a thing after you finish a life here, may not exist, because of how you understand the functioning of life, and how it's important to detach and how such an experience would influence the life path of a person, so you may not even be 'allowed' to do it based on those monitoring you, which could be your own higher self.
So there are all these little reasons around why it's not more common, but most importantly I think it ties into our path. Just like with ET abductions, we are not meant to know about them as if we did, that would change everything for us. That is why our memories are manipulated so that it doesn't impact our soul contract.
I think that Lai's session with Mary and Jesus here is a good example to refer people to, to see how history has been influenced by higher vibational beings that sometimes manifest in the physical:
The Cosmic Journey of Lai – Part 3 (note this is an automatically migrated article over to the new site so the formatting will be a bit off)
Topcis covered in the session (conducted in July, 2013):
-Joan of Arc and the task Lai had with helping her believe messages she was to be given
-The role the Pleiadians play with not only their interaction with Joan, but with many other interactions on Earth as well as with the shift in consciousness going on. The Sirians are also named as a primary group taking part
-The interaction and assistance Lai gave Mary while she was pregnant, and some very detailed information around Jesus’s birth and conception, as well as why he was sent to Earth in the first place
-Where Lai resides when he is not performing his tasks and roles
-Information on the status of the shift in consciousness/the event/GCE/the gathering, specifically around the timing of it and ongoing delays as well as detailed informationon what the cabal/dark forces/pirates are doing in relation to stopping specific events from occurring, to cause delays
-Information surrounding the earth changes relating to the shift
