i've had similar experiences. the most recent was when i felt the onset of sleep paralysis (attempting a WILD about 5 hours into my sleep). i felt my dream body float up, and stand facing the foot of my bed, grabbing both sides of my closet door with my hands.

everything was black, the only sensory input was the sense of being 'present', and the hardness of the door my hands were grabbing. as i have been conscious in such a state a few times, i tried to open my eyes.

a blinding flash of light forced me to shut them. i tried twice more, straining to see anything through the light, but lost consciousness, and slipped into a non-lucid dream.

Its tricky, this is one of the obstacles i am trying to learn how to overcome in my efforts. i'll let you know if i find something that works.
