I have on one occasion heard music coming from a street lamp, sweet child of mine if memory serves me correct. My next memory is being violently sick and then rolling on the floor with laughter and stomach cramps. Not an experience I wished to repeat.
The Sami in Sweden still use fly agaric to connect to their spirit world and ancestors, problem with that one is that the chemicals within vary wildly. One day you could eat some and have a nice wee trip, next one you have may put you to sleep for good.
In all seriousness though, steer clear unless you know what they are. I can recognise 6 different (edible) shrooms with absolute certainty and they are the only ones I pick. Even innocuous looking field mushroom (what you see in supermarkets) has some extremely poisonous and deadly brothers and sisters in the Agaricus family. They look very similar and field identification is very difficult unless you really know what you are doing, I wouldn't touch them!!!
Sad story a little while ago of a mother who made some soup from what she thought were edible mushrooms. They turned out to be Death Caps :-(
Your liver and kidneys can't process the toxins and pass them out, so they continually get circulated round the body. Each time they pass through the organs they cause more damage, until the inevitable happens and your kidneys and liver fail. No known cure and nothing at all can be done to help apart from palliative care.
Even some edible species have to be cooked to remove toxins, some you cant drink alchohol within72 hours of eating them (ink caps) or they can poisen you, and some, though are edible just taste shite!
