Had only a raw one picked from the east of The Netherlands while we were on introduction camp with our Artificial Intelligence student organisation back in 1998/1999.
I ate it after pouring a little boiled water over it and drinking that too and went outside to the Staten Bolwerk park (in Haarlem, The Netherlands) which was very near to my rented room.
There was a blackness that was nonetheless completely transparent and there were slight visuals that we like dark heraldic suns.
The experience suggests that the experience of amanita is generally quite different that that of psilo-shrooms, with which I had much more experience.
It's been suggested that the experience is much more deliriant than that of psilos, that sounds plausible to me, since I did plenty of them, and it was quite different.
