I do this thing where if I'm listening or reading a book I'll copy the facial expressions that are mentioned or repeat odd words or sounds that sound satisfying to me. This extends to things like if something "shone" I'll kind of sing out "sheen." Not really sure if this is an ADHD thing or what. It sometimes happens with films but is more common when reading. P.s. Audiobooks are a godsend when you love reading but can't deal with text!!
It sounds unique and fun! :)
