I'll give you a natural hallucination.
Go to the Mojave desert, or a desert near you.
Find a Peyote cactus.
On top of the cactus there will be a flowering. Inside there will be a "fruit" of sorts.
Place this in your mouth, and suck on it.
You will hallucinate for 3 to 4 days.
NOTE: This is dangerous. If you manage to survive these four days without cracking, you are a god. It really messes you up when you wake up, and you're STILL HIGH, especially when you expect to have come down off this high.
What they forget to mention in these moves is that when Native Americans go out on Spirit Quests, just before they go, they suck on the flower/fruit of a peyote cactus. THIS is what makes you see talking wolves.
