And yet you had the nerve to suggest that I might have played a part. You need have no worries on that score. The state of dissociation that you reached can be used most effectively. You blundered into it all unaware and unprepared, however. For shame.

If you recall, part of your mind was conscious in usual terms. You were capable of normal conversation; another part of your psyche was completely dissociated and waiting for your command. It floundered like a wet rag in a foul wind. … Since you were unaware of causing the dissociation to begin with, you were unable to find your blundering way out.

They do, sometimes on purpose and sometimes by accident. In some cases, your people have blundered through the apparent curtain between your past and present, and so have others blundered into the apparent division between one plane and another. Usually, they have been invisible to your plane, as the few who fell into the apparent past were invisible to the people of the past.
