repeated images or flashing of the screen will certainly start a
trance, but the effect
of the trance will have mostly to do with the content of the loop - or
the talking,
since you had your eyes closed. that said, some of the talking
probably had
inadvertent or deliberate embedded commands or command fragments which
could 'haunt' you for some time. for example, if the niagra scene had
in
there 'look at her go over that waterfall' 'she's going down again'
and so on,
this could have a rather negative effect next time you are standing on
top
of a building looking down, and so on. these kinds of hypnotic
commands
are really irksome and usually serve only to increase the sort of
stress in
life we all experience. trance abuse indeed.
