You wake up on the couch. It seems a bit strange, given you don't remember going to sleep there.
Then again, you don't remember much of anything right now.
You get up to shower and put clothes on, but you don't really know why. It's not like you have somewhere to be.
You walk to the bathroom, which is on the same floor. Everything is, and always has been. Your house only has one floor.
Luckily for you, the pipes still work, so you take a nice long shower. Nobody is there to stop you, so why not?
You finish, dry off, put on some clothing, and go look for some food. There's only one MRE left in the cabinet, but it's probably fine, since there has always been exactly one MRE in the cabinet.
It's spaghetti and meatballs, the only remotely good one. You pour it into a bowl, heat some water, add it in, and stir it with a plastic fork, the only utensil in your house.
You sit at your table and eat. When you finish, you leave everything on the table.
You go back to the couch and lay down, falling asleep immediately.
