The only ways to force an OBE are strong drugs or to almost die.
Without drugs or neardeath, an OBE is a voluntary act. But sometimes we can "subconsciosly" induce them, like a lucid dream.
I just want to know out of curiosity,
can Robert Bruces' Rope Method actully force an OBE,
or can it only produce an astral projection and lucid dream?
