I am sixty-two so everything gets easily tired. I have had sleep problems my whole life. I am a chronic sleep talker and sleep walker. Well actually I do not sleep walk too often when I am not drinking. But I had some severe sleep walking episodes as a child. Once where I was dreaming that I was going to my parents bathroom. I opened the door in my sleep and took the first step into what I thought was their bathroom. I fell all the way down the basement stairs. The two doors were side by side. Luckily I was not hurt.

I have often felt mentally tired. Sleep problems are one primary cause. There could be many causes not just dissociation.
