Welcome Rendar! When I read your original post here with your experiences I thought of the same idea as FryingMan (what an excellent, thorough post FM!), namely to "rehearse your 'I'm dreaming!' ritual/moment while awake." The only thing I would like to add to that is that before visualizing that moment and then moving on to your goals (both very helpful), you might also want to try simulating an RC that is indicating that you are in dream (indicating that you are in a dream while asleep in bed, with none of the limitations that we tend to experience while dreaming in the waking world, to borrow ideas from dream yoga.)

Some ways that I like to simulate RC's to show that I am dreaming include lifting myself up on my toes while looking up which can give the sensation of beginning to float off of the ground, especially if you have a ceiling nearby that you can feel yourself approaching (even if every so slightly) as you lift up onto your toes. Recently I was looking at clouds just above the horizon in the moonlight that were going away from me and thus appeared to be going down towards the horizon, which also simulated the feeling of me floating up not unlike stationary motion simulators like you find in some arcades. Another simulation I use is to take a finger from one hand and stick it out under my other hand to give the look of having 6 fingers. In a dream the extra or odd finger(s) are part of the hand. You can also simulate the finger poking through your palm if you hold you palm at the right angle. The idea with the simulation is to invoke more genuine feelings of "wow, this really does feel like a dream." When you are in a sleeping dream, the float will be way more obvious and perhaps you will feel some excitement upon thinking about the difference, but either way I think the most important thing for you is to seize the moment like FM said through a "just became lucid" ritual. There are so many fun, creative, and inspiring things that you can do when lucid dreaming.

Let us know if anything didn't make sense.
