Well, there is no substance that will, in itself, cause you to have lucid dreams. If there were this site would consist of "take this" and nothing else. Depending on the drug, some people will sleep lighter or heavier at night, causing them to have less or more dream time. Lucid dreamingly mainly consists, though, of your self recongizing that what is around you is not right or can't be happening.

I'd be careful if experimenting with any drugs or herbs as many of them, I believe, haven't gone through enough testing and could hurt you.

Anyway, those are my views. Let us know if you have any questions.
