Actually, it does work. But the tool has to be something that can fly. Socks don't fly! Kites do. Hot air balloons, even a paper airplane might work! It helps get over a mental block or mental barrier.
I once called 'Nimbus', the flying cloud Goku uses in Dragon Ball Z. (Just my own tool I tried once).
It didn't look the same and was just an orange spot light that shown in on the ground in the night where I was lucid dreaming, but when I stood in the circle I was able to fly. I just believed it could help me and it did. I only levitated and moved around from a standing position, but it worked. It helped me get over it, and kick that 'nay-sayer-attitude' that always makes me fall back again.
But this other time I summoned a go-kart! It was just a dinky remote control car, but when I stood on it, (not feeling it, but just in the same place), I was then able to scoot around in a sitting position and drive around. I didn't actually see the car anymore, but was moving from a sitting position, hovering inches above the street, using a pretend steering wheel. I even shot some rockets out the front like a video game and it was great fun.
I become a kid in dreams!
And why fly when you can drive? I recommend go-karting or motorcycling in dreams!
But either way, TOOLS HELP! Ask and hopefully they come. But it helps if they make a somewhat logical sense for their purpose. It helps you believe it will work.
