In essence, meditation can be described as a state of mind that is focused on an object of mental awareness that is a cause of inner peace. It doesn't seem to imply closed eyes, or even sitting still for that matter. Also, in dreams, everything is an object of mental awareness.

I've meditated a lot in the waking world. A lot a lot. Like 6+ hours a day for a year, then down to a few hours a day for a few years, and now at a more balanced 20 minutes a day (so I can maintain my health better). So I feel like I understand how to meditate quite well in the waking world. Only just recently I started trying it in lucid dreams. I've only attempted it a dozen or so times so far, and each time I've tried to meditate, I've immediately woken up as soon as I closed my eyes. Although, I have only tried doing fairly complicated meditations in my dreams. Next time, I'm going to start with a simple one and see how that goes.

If you have tried meditating in lucid dreams, do you keep your eyes open or closed? Also, what do you meditate on?
