Yesterday I was driving to a friends place for my weekly voice lessons and all of a sudden I had no idea where I was. I knew I was going to my friends place, but I didn't know if I was still on the right highway, where on the highway I was, nothing looked familiar. I looked to the sides of the road and ahead and I didn't see anything I recognized. I didn't know if I had passed the place to where I was going, or if it was still coming up. It was terrifying. This has never happened to me before.
