I had a friend (John) who went up a mountain to find his spirit guide on a peyote trip. He remembered getting to the top and dreaming of an eagle (why is it always an eagle or a wolf, why never a slug or wombat?).
Anyway, he woke up stark bollock naked when a man with a donkey walked past, laughing at him. John walked back down the hill, retracing his climb, picking up his discarded vestements on the way.
Do I approve? I wouldn't be stupid enough to do it, but I would not stop others doing it to amuse the rest of us.
