Hearing Hobby

Sometimes I hear a certain word, and in my mind a sound is heard. I find myself then spending time, putting other words in rhyme. I speak out loud so I can hear, the words sound clearly to my ear. Sometimes they come in easy flow, the rhyming starts, and off I go. Take a word like orthodox, there's three syllables it unlocks. So I pronounce it nice and slow, and paradox begins to show. I don't know why I tend to rhyme, but it happens all the time. Why this ringing in my head, even when I go to bed? I don't know why or even when; look out, here it comes again. One certain thing I know for sure, it's my hobby, there's no cure.
