How can I prove that my experience is not just a very vivid dream?

Dreams are constructed by the human imagination which struggles to maintain internal consistency. By definition the imagination is generally trying to come up with something new. It’s why in dreams you can walk in a building. Walk around for a bit then realise it has more rooms inside than would seem to fit looking at the outside.

so if you’re worried you’re dreaming check for consistency. Seal messages in envelopes and then randomly check later. Read a page in a book then check the same book later. In fact read a page in the middle of a book. Then flip 2 pages back and read forward to the page you just read? Does it match what you remember? Does the text naturally flow into the page you first read?

Long time ago after spending afternoon thinking about how people headbutt the unsurpasable walls of their problems, and somehow sometimes succeed I had a dream where I was facing a brick wall thinking that it's impossible to pass to the other side, and I said ''I know how to do it'', then I melted through to the other side. So, it's safe to assume it was a dream. LOL

Don't laugh too loudly. There may be no further theory to free us from the weirdness of quantum theory. Within that there is a probability of "melting through the other side"

I'll be back. (bed time)
