You go back the way you came –– you think. You can’t be entirely sure. Stumbling around in the dark for a while, you somehow bump into your own front door. As you fumble for the keys you remember that you left it unlocked.
Upon entering, you immediately see all of your books strewn across the floor, all of them open. You rush to check if your phone and computer are where you left them. Relief washes over you when they are, though they’re inexplicably unlocked and turned on.
