You'ld first have to establish that there was something to catch before you could try to define what part of the brain or process made it a type of receiver.
No, I wouldn't. It's your claim, you the burden of proof lies on you.
The film was an example to illustrate the concept that the multidimensional theories suggest, not provide evidence. The books by Lewis Carroll were used to explain why I was interested after over hearing discussions about other dimensions as a child.
No, at least not the way I read it. You posited your theory of multidimensional consciousness before you admitted it was based on a film.
This is what you said about Alice in Wonderland:
[A]s a child, I reread "Alice in Wonderland" and "Alice Through The Looking Glass" hoping to find clues on how to get to these other places.
Sounds like you were looking for evidence to me.
Did you read dlorde's linked article? This is what looking for evidence is actually about: examining all sides of any discussion.
Alas, given what you say next, you probably haven't read it and, even if you had, it wouldn't have made any difference:
It will take more than "there is no evidence" to convince me that I'm wrong
Even with what follows in that sentence, which I have snipped for clarity, that pretty much sums up your attitude, and is very much in line with what other posters have been saying to you. You have a predetermined conclusion, and nothing will shake it.
That's fine, but, as JayUtah said, don't pretend this is science. If you want to go down that path, you will have to answer another point I made, that you seem to have carefully sidestepped:
If what you claim is true, it would mean upturning every advance on scientific endeavour in this field. How could such a revelation be possible?
