First off thanks to everyone sharing their stories-it is helping me to see I'm not the only one that has had this type of thing. I've battled insomnia for years & it combined with mania has caused some pretty weird things. I went through a period where I saw halos & lights shimmering around peoples heads, I thought I was a witch with real powers & was paranoid another witch was trying to harm me, I believed I could "heal" people through my touch & I've felt like people on the train or bus are talking about me/plotting something & that I have to pay close attention to my surroundings & be on alert to circumvent a disaster. Once after taking a substance that I shouldn't have I became convinced I was insane & being held in a tiny dark room & that I would be trapped there for all eternity.
