A headache in a dream represents one's sins. Suffering from a migraine headache in a dream means that one should repent of his sins, curtail his plans, distribute money in charity, observe a voluntary religious fast, seek a spiritual retreat, or have a change of heart toward doing good deeds. A headache in a dream also means suffering from unhappiness and misery in one's life. A headache in a dream could also represent one's employer or supervisor.
