I don't think I have ever experienced sleep paralysis, but I have lucid dreams almost every night.
I somehow have come to realize they are dreams, but I certainly wish I could have some peaceful sleep instead of these bizarre dreams.
Your descriptions helps me understand the sleep paralysis state. I think that might explain many UFO experiences.
I have many UFO dreams in my lucid state (and I wonder where they are coming from).
That said, John Mack tried to focus on folks who were unlike you and me (if only because our experiences might be tainted by paralysis or lucidity of dreams).
He focused (as much as he could) on those who were wide awake.
Thx again for your wonderful comments. Helps me to broaden my understanding greatly of all our incredible human differences and experiences.
Stay in touch!
I certainly find the subject interesting. I searched for answers for years to figure out what was going on.
