I've never had as seizure but when i took a bit of harmala extract and snorted some melatonin i was having an extremely vivid, colorful, 3-D memory of childhood long forgotten when suddenly my legs begun to seize up and I felt this electrical like energy begin to surge outta my head, then it happened again. I was shakin afterward, but i didnt fully have a seizure, but couldnt of prevented it if i did.
