I didn't sleep much last night and was having a rough day and then I had this weird episode. I've never experienced anything like it. It felt like I couldn't move but I could. My skin felt so tight and I kept trying to wring my arms like a wet towel. I was digging my nails into my arms and clenching my teeth. I was so scared I still am. It has calmed down now but now I'm in slow motion. My walking is more of a shuffle and my head is kind of hanging down. It's taking a long time to write this. I don't know what is happening. Has anyone experienced this?
