Nap lag
A temporary disruption of bodily rhythms caused by a not so refreshing nap. You'll find yourself in a state that holds the middle between sleeping and being awake. 

Effects such as drowsiness, disorientation, confusion, nausea, feeling crappy and looking particularly cute are not unheard of. To date there is no known cure for nap lag.
