My first happen so long ago it's blurry. I was in high school walking down the hall when suddenly my hair and nails were dead things I needed to get rid of and all the other kids didn't realize that they were walking around with dead things on their heads. Fortunately it was brief and I was able to hide it. My next one I was 27-28 it was mystical and beautiful. It might have been brought on by my not eating and becoming underweight because my anxiety was so high. Anyway I could see what the area looked like before humans came and destroyed the land. Like if I was on 3rd floor I could see though the floor to see animals grass and trees under me. I could manipulate time and see into the past, future and space, watching stars being born and going nova.
