So, I was wondering if anybody else noticed this.
When I sleep and have LD on my left side, my dream and everything I do is more kind of action-packed. Things like flying, fighting come sort of easier.
When I sleep on the right side it's more kind of, about the beauty of the whole thing. Good conversations, coloring the sky, stuff like this.

I read that when we sleep on the left side it activates the sympathicus, fight or flight nervous system. Which is like when you get scared you will either fight or run away. Also they did research and most people have nightmares when they sleep on their left side.
The right side activates the parasympathicus and that slows down the heart beat etc. A more peaceful kind of sleep.

Now, sleeping on either side doesn't effect my lucidity. Just the contents of the dream and sort of what I'm more likely to do in the dream.

This is part of the Tibetan dream yoga. Men should sleep on their right side, and for some reason, women on their left. I don't understand why the difference depending on the gender, but I'm male so it's right side for me anyway.
Also what I found interesting is that in Islam, muslims should sleep on their right side.
