Hi Meiko2847! Good question. I will attempt an answer and I hope others reply as well because I don't have all the answers!

I think it's a good sign that you're starting to think those thoughts in dreams. For example I had a dream the other night when I had a sink faucet that could give water. But it wasn't connected to any pipes. So I just told myself that they must have invented "compressed water". LOL! And I have lots of other moments like that.

So my favorite advice I've heard about this has been to try to see it as a positive that you are even having that glimpse of consciousness.. "Huh? a portal? Oh, never mind.." as opposed to berating yourself afterward like, "A portal?! How could you miss that?!" Be like, wow, that's so cool that you registered some dreamlike quality of that event. (And give yourself a pre-lucidity point!)

How many RC's are you currently doing a day? It might be plenty. moving from pre-lucidity to lucid realization might just take time. But that's up to you if you want to do more. Also there is general awareness like making a list of moments such as these, which could only happen in a dream, to review.

EDIT - those are just my suggestions or how I think of it
