Actually, the investigation session does not exist!
Instead is considered what we call an investigation protocol in regressive hypnosis. Before asserting that an information is founded, we need to create a large quantity of sessions with different people unknown to each other, to reduce the contamination risk of the rational mind.
It is as well necessary to recreate the same hypnotic ambiances/mental co-creations in an univocal direction. This information is highly contaminated by the quantity of dimensions, densities, mental structures and believes through which they transit as well as the beings intercepting it and using it.
The only information seriously considered is the one coming from the large amount of sessions explained above. Thus it is the communal information from all the trials that will be considered (or with a low percentage error tolerance).
