Sometimes when i wake up in the morning I wonder if I have betrayed myself while I was sleeping. Did I shout out things that should not be said, or worse things that I don't even know about. The things that are locked up in the sub-conscious. The fear develops over time as you know that you are not the most silent sleeper. Ocassionaly you say a word or a name, let out a yell, or violently move. The fear I guess is that you will sleep walk or something. Aren't think locked in the sub-conscious for a reason?
