Sue mentioned a floating scene in Foundling, but I don't have any recollection of that time so maybe that incident would shed some additional light on the topic.
As far as I recall, in Foundling he was also having a nightmare when he woke up in a sweat and fell back onto the bed. Or, at least, he was tossing and turning, thanks to the globe reaching out to him.
Course, you might want to check that one out, as all I can really clearly recall of that scene is that Clark was bare-chested at the time....
