is meditation just lucid sleep

[astralee]

except we donte control the dreams in lucid sleep we observe them instead.

Meditation is meditation.
It's focusing the mind towards a single thought... or towards a variety of thoughts.  <-- HA!  How's that for ambiguity! 

"Lucid Sleep"?
Are you referring to lucid dreaming?
It's simply being aware that you're experiencing the non-physical while you're experiencing it.

[astralee]

yep  it feel like mind awake body asleep at times.

I have experienced many lucid dreams. I love dreaming.
