This Awareness indicates that it appears the brain functions in humans do not shut down totally, and chemicals continue to circulate along with certain electromagnetic activities which tend to influence dreams.
This Awareness indicates that it appears alien types have similar functioning brains, along with the chemicals influencing the brain activities so that they too could be said to dream, although it appears the Greys do not have as vivid types of dreams as humans. They appear to have certain patterns that change.
This would be more likened unto a kaleidoscope, although quite different, since the dreams of Greys tend not to be colorful, but the patterns in the dreams of Greys tend to be somewhat likened unto changing shapes of shades of gray, rather than dreams of friends and associates or struggles in the same nature that humans might experience.
This Awareness indicates that the Reptoids are closer to humans in their manner of dreaming.
