Some random blogger and neuropharmacologist has theorized that in some cases where brain damage or dysfunction is involved, people are unable to remember dreams or to have lucid dreams. Judging by my own dream habits, it may be true. While my dreams are most definitely extravagant, I only remember very small portions of them... say a couple seconds worth, if I remember them at all which is pretty rare. And, even though my dreams are horrifically terrifying, I have absolutely no feeling or emotion during them or when I awake afterward, which I thought was normal, but apparently it isn't. My memories are about the same way. Actually, if my dreams weren't as surreal as they are, I would easily confuse them with memories. In lucid dreaming, they say you're supposed to be aware that you're in a dream. There's no breaking 4th walls in my dreams. I'm not even aware that something is unrealistic... until I wake up, of course.

So, I was wondering if anyone could give me a comparison? Are they vivid and realistic? Do you have emotions during them? Can you feel anything physically? Etc. I know dreams are difficult to remember for anyone, so maybe I'm just exaggerating. On the other hand, despite that I haven't found any other research on the subject, this blogger had some convincing science to support his hypothesis.
