I've also been lucid dreaming for years. I used to do it unknowingly as a child. I would just realize I was dreaming and usually wake up. I've always had this severe questioning nature as well, especially about reality itself. I would look at an insect with a magnifying glass and see how strange and beautiful it was and the first thing I would think, "Is this even real? Am I awake right now?"
I have been able to remember more of my Salvia experiences over the last couple years in particular. But there's always something deep, something that feels incredibly important that eludes me. And the beings themselves aren't very encouraging, they playfully tease me like, "Look at him! He can't remember his lessons!"

Why I posted about the dosage is because I find that I can remember more with lower dosages. When I smoke plain leaf in particular I can recall pretty much the entire experience. It's just getting the dose right so that you can be propelled far enough, but still retain memory.
Very fascinating subject for me, the role of memory.
