No, they don't.
A WILD is the transition from waking to sleep without loss of waking-life consciousness. Period.
It is
not about "intense physical, auditory, and visual hallucinations," and saying that it is marks both a grave misdirection from the truth, and the truly sad state of LD'ing on these forums. WILD is, simply, a way of becoming lucid and, yes, its path
can allow you to witness the
absolutely normal physical processes your body goes through every night, but those processes can easily be ignored and certainly hold no bearing on the success or validity of a WILD.
I've had thousands of WILDs over the years, and I can safely say that the vast majority of them occurred without
any intense physical, auditory, and visual hallucinations. Of course, I did start LD'ing long before the Internet was invented, so I guess I never had opportunity to expect them, or dare I say, to look forward to them!
WILD is a state of mind; an option for enjoying lucid dreaming. It is absolutely not a vehicle for "SP," HI, vibrations, and whatever other "
noise" might be encountered during a WILD attempt. Yes, those things can and do occur, but they are not the priority, and they certainly are not the way "WILDs make themselves known." It would be real nice if we could all just step back and erase just some of the sensationalism about the "noise" that has come to fully replace the dream as the real goal of WILD. It would be nice if newbies could be led to understand that WILD is about the
dream, and not about the stuff they might encounter on the way to that dream.
Sorry for being so harsh, Cmind; DV's was enjoying a brief bout of sanity for a few months regarding all that noise, but that sanity has been losing ground lately to the excitement that comes with the noise ... your post was a sign for me that we're once again right back where we started.
