It's just a matter of pygmalion effect. Your expectation is that you cannot fall asleep during lying on your back and so you cannot fall asleep and you also most probably try to focus on falling asleep too much which would be counter-productive in your usual position as well, think about it this way, the easiest way not to fall asleep is trying to fall asleep
