While sleeping, my feet aren't securing my body to the substratum.

You raise an interesting point.  I agree that a limited upstroke tends
to rule out a "ground-up" origin of flight, because scenarios such as
WAIR emphasize the role of a full wingstroke in the incipient stages.
However, there are other reasons aside from roosting that might put
small paravian theropods at elevation.
