About a a year ago when I had wicked hypergraphia, I was seeing writing and certain characters all over the place on certain textures. I also see very vivid faces in wrinkled clothing under certain conditions.

These aren't hallucinations though, they're called illusions. I just have very peculiar perceptions of things I'm actually seeing. I wish I could trace or outline them. The images no one else could see were much better than what I can draw
