Anybody have any experience with any compounds that promote extra vivid / intense dreams? I experienced that when I first started taking Metorpolol for high blood pressure, but the effect fades over time. I find it quite enjoyable though - there's nothing quite like a vividly intense / surreal dream so long as it's not an outright nightmare. Anyway, I've been wondering if there are any safe / over the counter substances that can help promote a similar effect. Found this Wikipedia article which is encouraging. But would love to hear any first-hand experience from fellow HN'ers.
