Hi Tom

If you were clanging, people would definitely have pointed it out to you. It is very obvious to lay people. People don't randomly rhyme all of the time in 'normal' society.

Same with neologisms: if you were doing it a lot, people would be asking you what on earth you were talking about.

Other signs of thought disorder can be much more subtle and lay people wouldn't really pick up on them much, but clanging and neologisms (and word salad - the most extreme example of thought disorder) are pretty noticeable. So, personally, if no one has asked you about them, I wouldn't worry about it. But, as ever, if you're really concerned about it, it's best to consult a psychiatrist/therapist IRL.

All the best
