This is the man who bought this lion as a cub in the 60’s and then when it got too big he let it into the wild. 10 years later it was the alpha male in a nature reserve in Africa and it was really violent. The guy went to see it and it walked up to him and gave him a hug.
Yes, dimensions exist and they are layered. They are also not a hierarchy. Just because we here might be 3D doesn't mean someone who is 4D or 6D or 12D is better than us. They might have more personal power, will almost certainly be older than our current body, and maybe have retained a bit of wisdom from memories that are denied us... but they are not better than us. -Tanaath
