A few times each day, I seem to be in one place and the next thing I know, I'm somewhere else. I remember where I was at the start, and I have no idea when I got to where I was.

Many times, a few hours per day, I will just hear classical piano music and nobody else will hear it. I have never heard that specific music nor do I recall ever searching for classical piano music.

Four days ago, someone who I have never met before approached me, and when I asked who they were, they just said that we met the prior day and that I was very polite while conversing(Two things that I normally would not do). They also commented that my style of walking had changed since the prior day.

Do I have a dissociative disorder? If so, which one? If not, then what could I have?
