I would say that my thoughts are normal. Very clear. Especially when you have strong lucidity and a lot of control in the dream. Something to keep in mind is that lucid dreams do not last long. Like 3 minutes up to maybe 20 if you are lucky. For me my longest one was probably 5-6 minutes. There's not a lot of time to analyze your thoughts, its kind of like this surprised "oh shit, I'm dreaming what should I do? Fly!" and then go. Or look just look around. I would say that my thoughts are minimal like if you were doing something you have never done before just taking everything in. Hopefully that helps!
