Actually, many people have dreams that occur later in life. For some, the time is relatively short others it is long and some people don't recall the dream. There is nothing wrong with having this type of dream.
Did you by chance mean to ask if your dreams showed a type of aptitude for the arts? If so, I would say it did. Everyone has the ability to preform the arts at some level. Some people are natural at cretin things. Either way, your dreams appear completely normal.
