I mean that I don't recall having dreams. I assume I have them, everyone is supposed to, but unless I wake up during them, I don't remember even having a dream at all. (If I wake up during, while I might forget the dream itself, I'll still know I had one.)
If I think about it, I can recall maybe 5-10 dreams I've had over the course of my life, but that's it, and usually it was because it was a painful dream.

... for kicks and giggles, there was one dream I had when I was ten or eleven, where I don't remember the dream itself: I just remember walking into my parents' bedroom in the middle of the night carrying a pair of sneakers in my hand, and I stood there and said, "Bilbo's dead."
No one moved.
I was like, "Why on earth am I standing here, and why did I say that?" So I took my sneakers and went back to my room. I have no idea what the dream was about.
