I've been reading about people's attempts to lucid dream, and the people who are new to it say they are lucid for like short periods of time. anywhere from seconds to a couple minutes.

I don't understand how this is possible. In my lucid dreams i'm usually lucid like...until i wake up. I don't get how you can only be lucid for a few seconds. Maybe you're just not fully lucid? Because in my lucid dreams i'm fully conscious as if I were awake. There's no chance i'm gonna just forget i'm dreaming, because my brain is working perfectly fine.
