hmmm
well without a better descrition, im just gonna cover the basics
is the entire set of finger leaves inverted, or the individual leaves?
if the leaf stalk has rotated, to orient the leaf set downward, this is light seeking behaviour
are the leaves regular and inverted, or oddly shaped and curled?
oddly shaped and curled is usually either a ph issue, or an over watering issue.
if all your leaves are excessively ridged its over watering.
are they always upside down or do they rotate randomly while screaming.
random movement with screaming, is normally caused when your house was built on a native American burial ground.
dont go to sleep, have kids, or turn the tv on, in fact dont go home.
youll be fine.
