Hello another cliché: I guess I can't say whether or not your dream experience is common or not. I do think that medications can have an impact on dreaming. I know if I forget, on occasion, to take my SNRI, that night I'll "go to the movies", as I like to say!

It may not be you're not dreaming but rather, for some reason, you're not remembering them. Have you ever looked into the practice of "lucid dreaming"? I have not. But I understand that it is a technique by which practitioners learn to control their dreams. I don't know how well it works or how difficult it is to learn. Perhaps other PC members may be more familiar with the technique. It may be worth checking out.
