I get the sentences/particular words thing in my head. Have mentioned it to individuals on occasion but it's only ever been received with dismissal so I thought it was just a personal, unexplainable quirk of mine. You're the first person I've seen referencing it. I can inexplicably become struck by a word or short phrase such as "conjugational recombination" and have it rattle around my head for hours. I can get on with my day but say I'm at work and it's a day with an odd/previously un-ushered phrase stuck in my head, I can get some tasks done as normal then in between tasks my brain is as if it's enjoying some rhythmic/phonetic quality of the phrase as it cycles it repeatedly through my consciousness. It can get old very quickly but I tend to have no control over when it leaves me. Doesn't happen very often thankfully.
Music has been a massive part of my life since I was about 10. I'm always tapping out a rhythm, or have a restless foot/leg. My wife has called me Thumper after the Bambi character for as long as I remember. I don't tend to notice if I have a restless leg at work unless I'm emailing then it's obvious and pretty constant; but at home it's pretty much all the time. Even if it's just a toe doing an occasional stretch or whatever. I try not to "BE Thumper" when I notice it but then I find I'll end up sort of pushing or pulling a foot/leg against something ie my other foot/leg. There's less noticeable movement with that but definitely still something going on.
Are these behaviours ever associated with allistic people? I would have thought the phrases thing to have more in common with tourettes given my experience of it is that of it being involuntary.
