Anyone else just not have dreams anymore? Is it possible to start dreaming again?

I used to have many dreams as a kid, I even have a memory of being lucid in one of them. But as I got older, my dreams started becoming much less vivid and eventually stopped all together.

I still sometimes have dream-like experiences when I wake up in the middle of the night and go back to sleep, but they're very blurry and incoherent. More like a distant memory of what felt like a dream, without actually remembering any of it.
