I have trouble, though I’ve only tried a few times. I was lucid a couple of nights ago and tried it. I looked to my right, saw a window and flew through. I was airborne, and not really moving forward, and pretty nervous about being off the ground! This incredibly strong tingly feeling went through my body and suddenly everything turned completely black. I couldn’t even get my hands to appear in front of me, until finally I ‘gave up’ and let myself wake up… but ARGH it was a FA!
That was weird, but not as weird as last night’s normal dream… where I cut a lemon in half, held a half in each hand and this enabled me to fly around freely.
