Lucid Dreaming and OBE Discussion Board

I make a simple research with asking a friends of mine about the lucid dreaming and out of body travel.
One friend told me that before couple of years 3 teachers in the university that she work have great success of OBEU. But she see that all 3 have become crazy, aggressive and mad. And they are in hospital. This is real story i just want oppinion about this. Is this possible? I think that this could be possible only if people cant control them self.
What you think?

The phase state is not to blame for the teachers losing their marbles. Their problem was already inherent in them. The practice of phase states of the mind is safe. We don't recommend it for those who already have trouble telling the different between what real and imagined or have a propensity for psychosis.
