Hey everybody

I got a friend who is deep into yoga and meditation, according to her, some of the higher level 'yogi masters' say that for someone who is not well trained, lucid dreaming and especially OBE's could potentially be very dangerous because we may encounter something we don't understand and I guess left mentally scard or somthing

N e of u guys hurd about this at all? Or have n e of u had n e related experiences u wouldn't mind sharing ?
