I've been using an undersink RO system by Express Water for years now, it has 11 stages, including UV and remineralization. Works really well. But I didn't switch to fluoride-free toothpaste until just recently. After only about a month or two after making the switch, I started getting dreams again, consistently, every night. And I don't get stoned often, but I do sometimes partake with friends, and more recently that's been hitting a lot harder.
I really wonder if there's merit to the claims around decalcification of one's pineal gland. I actually never looked into it, I don't even know if more dreams is considered a result of cutting out fluoride, it's just... A part of me didn't like that the government insists on putting it into the water supply, and so I just wanted to cut it out. But if that's true, if that's what they're doing, holy shit. They're literally stealing our dreams... And they do that in so many ways.
