They are good for meditation, and meditation is good for lucid dreaming. I use it and really enjoy it, even if i dont have a LD that night.

thanks for the explanations man, but i would wish to know that are there some more ways to get of the solution for it?

I know a while ago years now there was a fake batch of kratom, substituting a different species of Mitragyna for the real stuff, so I would be wary of vendors potentially trying to sell off a "bad batch" before people catch on.
