Does the way you sleep have any symbolism at all?

For the last few nights, I've been waking up at around 4am. My whole life I've been a "sprawler." I've kicked, strangled, flailed, and spoken in my sleep. I've always been a bed hog, but these last few nights I've awoken to a strange sight. Each night I've woken up and seen myself neatly parallel to the edge of my bed and super close to the edge, without being uncomfortable or the feeling of falling off. It's unusual, so I guess it's normal for me to question what it means.
