This was a personal experience:
I taught HypnoBirthing classes for
years. One brief 10 min trance
involved tasting a lemon in a kitchen.
(The purpose was for the moms to
experience how their thoughts
create their physiology.)
I usually go into a light trance
whenever I'm with clients, so I
always visited a kitchen also,
even while talking and leading
the class through their experience.
It was always the same kitchen and it
was unfamiliar to me. I was curious...
One time when I was auditing
the teacher training, I decided to
indulge myself and really take the
time to explore that kitchen while
the trainer led us through the trance.
I suddenly 'knew' that the kitchen was
in a house in London during WW2.
My name was Violet and I worked in a
woolens shop. (In my current life, living
in the USA, I had never heard that
term.) I explored the house and the
neighborhood and travelled on a bus
from my home into the city and went
to my shop.
I also knew things about the RAF
because my husband was a pilot.
Meanwhile, the trainer moved on to
other things while I was still engaged
in my exploring and I popped out of
