Thank you again!

I'm not at the top level of lucidity in my LDs, but I do remember certain dream goals and intentions, even without the use of mnemonics. Touching something "invisible" was a definite intention, and although I didn't think of it as summoning (because I had no plans for what exactly it would be), of course you are correct that it is the exact same mechanism.

It is always interesting to see what my dreaming mind comes up with when I don't give it specific instructions. In my first DJ entry here on DV, I think I used something similar to Waggoner's things to ask yourself, "Show me something interesting!" - in that case simply because I couldn't think of anything, and I had recently read that list. I think that if you're lost for ideas, it's better to just let the dream come up with something for you, rather than struggling to think of something specific. I would be interested to hear about your experiences in this area? Do you ever let the dream take over because you run out of ideas? And can you keep your lucidity if you just observe (I suppose that means even less involvement than the above-mentioned "open" summoning), or do you have to interact in some way?
