So, for the past few days, I've been having these 'lucid' dreams, where I'll tell myself I'm dreaming and proceed to do things I'd do if I were lucid. But I have trouble flying, and the dreams are fuzzy afterwords. And I don't realise some weird things, like a talking walrus, or people appearing out of nowhere, talking to me, then disappearing.

Any reason why this is happening, and how to turn them into full lucid dreams?
