Just for those who are interested, other anti-cholinergic deliriants seem to be good dream enhancers (and sleep aids) too. I had a bit of a deliriant binge a while back, and while they're not exactly very fun drugs while you're on them, I had some really really crazy dreams during that period and for 2 or 3 weeks after I stopped using them. I was having 4-5x more dreams each night, remembering at least 3 dreams a night (I normally don't remember any) - and they were very vivid and abstract, sadly though I found the deliriants dramatically hindered my mental abilities for a month or two after my binge, so I'd recommend anyone doing this, whether you use datura or something else - to keep the doses low, I find regardless of the dosage the dream benefits are there, but the higher you push it, the more negative side effects, both long and short term.
