I had a nightmare last night

I was causally checking the price of Eth when I noticed I couldn’t see the graph. I thought it was a glitch as the screen was just a white. Then I noticed a jagged vertical red line on the left side of my screen. I kept scrolling down to find the bottom but I couldn’t find it. Giving up on scrolling down I looked at the price instead and it read £0.90 per Eth. The sudden panic that set in woke me up and all then was well.
