To address what u have said (according to what projectors have
reported and believe thus far):
The leaving the body part is sort of an art, there r numerous
methods and one has to try and find his or her best method.
About Meeting spirits.. if u have an OBE, what happens is that your
consciousness inhabits wat is known as the Real Time Zone, which is
the astral version of our physical world.. u see everything as if
it is, except they r affected by thought and time fluctuations.
Meeting spirits isn't scary when u realise they can't do anything
to you that you can't do to them, they're basically the same as
u!
The part about getting lost, what i read is that as long as u r
alive, there is no way u can escape your body, even if u wanted to
leave permanently u will be pulled back instinctively at the
slightest hint of danger or fear.
