Is it worth recording your dreams?

Something told me that recording dreams would improve my memory, keep my brain active and improve my dream recall. There are some “dream journal” apps for recording dreams these days. One teen magazine recommend one app like that, saying that: ”...it is specially useful for writers who want to get more inspiration”. But is it worth recording my dreams?

A bit background of this question: last night I had a very good dream which inspired me a lot for my writing. And I was thinking about if it was worth recording dreams of that kind next time.
