Does anyone else have the problem of controlling their thought commands? Where you think to yourself in a lucid, "What if THIS happens?" and just as you think it, it does.

My problem is gravity. Usually as soon as I go lucid my body's gravity gradually disappears. It goes to the point where I can't walk and I'm just floating there. I have to push off thinngs to get places.

But yeah...anyone else sometimes struggle with unintentional thought commands and does anyone have some tips for me? I just can't seem to convince my dream self that gravity works.
