Salvia is not physically addictive, and also very unlikely to be psychologically addictive. But anyways I can see what alfy984 is trying to say... and I believe that dreams could be just like hallucinations except in dreams our bodies are paralyzed making us unable to act out the actual actions. Obviously Salvia isn't for everyone, and should be taken only by people who know what they are doing. Anyways, I think that Salvia could enhance our LD experiences and inform us more about the mysteries of that other world.
