As the other poster indicated this sense of being detached can occur in other settings where drugs are not present.
When I walked the Camino de Santiago, I felt a major difference in interaction with other people and detached from the rest of the world. At least for me the experience gave me a megadose of a kind of empathy for other people I hadn't often experienced before. This combined with the fact of taking off each day not knowing where you would stay or what your sleeping conditions would be created a powerful sense of detachment from the cares of the "real" world.
