I'd like to find some good documentation on echolalia. I've said before that I've really not paid a lot of attention to myself, but over the last year I've increased that. So, I'm having a difficult time with seeing if even a little bit of echolalia would apply. Although I imagine I would know by now something was off!
Earlier today, I can note that after I heard a dog inside this apartment bark, that I had an urge to do such as well. I also remember as a child I used to really get my dad mad at me. He would say something about an object of some sort, and I would reply "I'll be a(n) -insert object here-". For instance, if he was looking for the can opener, and he mentioned it, I would say, "I'll be a can opener!". I still do this, and only when people are looking for/need something, but not nearly as much as I did when I was a kid. I do know that I get impulses to blurt things out occasionally, but I tend to catch myself (not always unfortunately). I don't remember if these things are things I've heard before or not. As far as I know, these things could simply just be impulsive behavior.
Another thing I'm curious about is the constant music in my head. I always have music playing in my head. The odd thing about it though is it is usually only like 3-5 seconds worth of a specific song, that repeats itself over and over. I can't turn it off. It is usually never a distraction, but it has been before.
