I am quite surprised that Amanita Muscaria "Fly Agaric" has not been mentioned as I personally believe that this is the very best substance for inducing lucid dreams. This entheogen is known for putting it's user into a comatose state with the craziest and vivid dreams you can imagine. I have gone to sleep on this mushroom and experienced extreme time dilation and distortions. One some occasions after awaking in the morning I felt as know I had been asleep for weeks. The depressing thing about lucid dreams is that once you become aware of the dream your world starts to vanish within the dream consciousness and it is not long before you awaken.
You will have the most restful sleep ever if you take this before bed and the afterglow "high" will persist for the entire next day. Muscimol the active component is also non addictive and non habit forming. This is the best medicine for sleep disorders in my opinion because if you take enough you must go to sleep. I have seen this mushroom in my dreams which suggests that it's spirit is behind the experience. It has been used for over 10,000 years and has a strong relationship with humans. I have found that drinking your urine in the morning will cause you to fall asleep again and this can be repeated a few times and you will pass the heck out each time lol
You can create tinctures from this mushroom in order to get the most Muscimol for your money or efforts in picking it. I have taken this mushroom in the past every night for months on end so for those who believe this is a toxic substance you should know that it is perfect, better then opioids I believe especially in combination with Chamomile (only used oxycodon). Once again, it's not habit forming. I haven't even consumed it in a while. Please take low doses and you will dig this mushroom. kids taking shamanic doses are the reason this mushroom is so underrated. It is also one of the most understudied plant medicines. it relieves pain and is a powerful analgesic with the right dose There is practically no information at all on it's medicinal use. My body tells me that it has medicinal properties however. You can even use it as a food source! I have not tried some of those other medicinal plants like "African Dream Root" so I cannot comment on that. Perhaps those are even better then Muscaria for lucid dreaming. What do I know anyway.
