in my case i have a very strong internal echolalia, as in i get stuck with a phrase or a specific thought, song, word, ecc... which i find very annoying, though I dont know about external echolalia, I never noticed
Same. I often wake up with random songs going through my head in the middle of the night. Sometimes it’s not the same one that was looping when I went to sleep.
I think I'm lucky. If I have a song stuck in my head, it usually the entire song. Unless it's Kill the Poor by the Dead Kennedys, then it's just "Kill the Poor!". GAH
