would it be possible for human consciousness to temporarily become aware of the information contained in this higher dimension

I would like to start off by saying I am not trying to attack you, you have some very wonderfully thought-provoking questions and ideas here.

I think I understand what you are getting at. Everyone is entitled to their own perception and opinion, and I strongly encourage you to come to these conclusions yourself.

I have a lot of experience with psychedelics, strange phenomenon, meditation, waking dreams, and strong feelings associated with them.

However, even though I may feel as if I had just experienced a past life, I try to constantly question and ground myself.

We should not underestimate the power of the human brain, and its ability to hallucinate. Even otherwise totally sane people can have benign hallucinations, which are usually associate with a strong emotional feeling.

I would personally like to think that most ghost stories, alien abductions, or visual miracles are benign hallucinations. When I bring this point up (take in mind, it is my opinion, and it's totally okay to disagree with me) many people tell me

"but there was no way it could have been a hallucination, it felt so real."

To which I say, exactly. That is the definition of a hallucination. They feel completely, if not, more real than reality.

I'm still a very spiritual person though, and I think that psychedelics, and meditation can be an excellent tool for looking deeper into your self. As well as asking big questions, or looking at things from a different angle.

Just my take on things, I hope my comment was relevant to your discussion.
