Advancedld.com is not up and hasn't been for about 6 months now.
ZenVortex, as a natural lucid dreamer as you would call it, I have only ever known fuel in the tank.
Though I know people that have gone from 'no fuel' to frequent 'natural' lucidity, just through changing underlying daily perspectives, listening to "lectures on how easy it is".
I have not read a single tutorial on here save one on Astral Projection, yet maintain a lucid state through dreams at will.
I know nothing of Neuroscience nor lucidity supplements, though if you believe you have found the reason for self-awareness and awareness of awareness please do explain instead of directing towards a book.
If you really have, then you have not only made some supplements highly creditable but also found the secret to life.
Thanks.
