Flying feels brilliant, which isn't a spectacular description, but its the only on that comes to mind. Sex feels like sex: also brilliant (hopefully). As being lucid usually includes a large amount of vividness, any antics do tend to feel real, though there is variation among dreams. Everyone's got their own reasons for moving on to other things, but I personally enjoy both still. Never used a nova; bare bones WILD works and I'm sticking to it.
