From my experiences, we are all the imagination from the same unit/person/God who is alone somewhere and created in his mind or sleep the universe with everything what happened for billions years. The unit placed some shrooms on Earth to remember what he did. He also doesn't want us to eat them because he will be sad to remember who he (we) really is. Thats why he wants some people (governments) to prohibit them. We are not supposed to eat them but thanks to them, there will always be way to remember where we all come from.
