That could be an isolated event, since you do not mention any other symptoms or problems, and it seems to have responded to Ibuprofen, since you do not claim otherwise. If it recurs, it could be the onset of a migraine, "Migraines respond to sleep," and at which time it is wiser to consult a doctor, preferably a neurologist!
if it does not recur do not worry about it.
