Today when taking a nap I stumbled upon something that might be useful to someone...

Once HI has started a little, imagine you are opening and closing an umbrella. For me, a certain opening of the umbrella would bring clearer imagery, the umbrella would pull up on my hand, and I would float a bit in my HI.

My guess is since you are familiar with the feel of an umbrella pulling up on your hand due to wind, maybe someone can use this to somehow transition into an LD where there are already flying/floating.

I wouldn't know how to use this for LD'ing though. Although I get pretty vivid hypnagogic imagery, I have yet to induce a lucid dream after years.

I Hope this can be useful to someone.
