I do believe that all the information of the infinite is available while dreaming or even from hyperspace. In fact, I believe it is even available while dead sober here in the "material world."

According to the Holographic Universe model, every part of the hologram contains all the information for the entire thing. Think of how every cell in our body contains the entire blueprint for our full form, and not simply for the cell that it is.

While it may stretch the mind to imagine infinite information, it is not so hard to get to the idea of a human collective unconsciousness. Even back in the dark ages of the 1800's people already grokked this concept, as well as the existence of archetypes. With what we understand about multi-dimensionality now... there is really no limit.

As I see it, it is pretty tricky to access, and one's ability to interact at that level depends on your consciousness, current level of lucidity or awareness, the limits on what you believe to be possible, and other such factors... but it is doable. In lucid dreams, it is easy enough to will yourself to find someone or some archetype of someone who will oblige you with answers to your questions... given that you can remember what they were when in that state.

The REAL problem is bringing the information back with you. There is a very potent border to cross when you return to this reality, and much dream and hyperspace info is rather difficult to remember when you do. Some mystics call this the amnesic return. Dreams can evaporate into thin air, and often the really juicy info just never makes the transition at all. As it is, we only remember a tiny fraction of our adventures... and I guess we agree to certain ground rules for this waking dream theater.

I would guess that it is somehow forbidden to bring certain info with you that would upset the balance here. Furthermore, I don't think that any being high enough to tell you the future would be interested in helping you become more attached to material things by giving you winning lotto numbers. The cure for cancer will probably be given to someone in a dream (the way many scientific advances have come), but I would guess it would be someone whose consciousness is already busy night and day with this problem.

Who knows?

I don't think there are any limits though, and I have learned that there are tricks to holding onto and "smuggling" contraband cosmic information. So, you should play with it and see what gems you can smuggle back from dreamlands. There is literally no end to what various entities, your own higher and future selves, the cosmic intelligence, and others might bestow upon you. Be sincere and forthright, and they will respond in kind.

And if you are lucky enough to enter a cosmic library or Akashic storehouse... see if you can figure out the Dewey decimal system there. Hint: it works with willpower and intention.

I believe i did on my first breakthrough

I found myself in what looked like a giant library
Endlessly long room
Very wide. Ceiling so high i couldnt see the top of it
I heard two voices one was asking a question and the other was answering it
I recognized the askers voice as my subconcious and the other voice seemed to come from everywhere
First thing i thought conciously was this must be where edgar cayce went so i can ask any question i want
I somehow knew my subconcious had already asked 5 questions and was given answers although i couldnt remember the questions nor the answers
I thought. If im here.and can ask anything. What should i ask
The bam. Back on the couch with a feeling that i saw all the events that would ever take place in my life before i chose to have this life amd suddenly believed in reincarnation.
Maybe it was the akasa. Maybe not. I tried to go back to access it a few mpre times but always wound up somewhere different
