Last night i started having a headache that slowly started making me hallucinate, and i figured it was just my sinuses until i started puking. help.

Migraine: It has been estimated that approximately 70% of migraine headaches overlie the sinuses and are triggered by changes in barometric pressure. These patients actually suffer from migraine but usually are diagnosed with sinus headache and use over-the counter vasoconstrictor (nose spray) agents for relief. Rec.: see orofacial pain or headache specialist for diagnosis and management. Good luck.
