You find yourself with a weird book.
You feel like you've read it, but you know you've never seen it before. You read it cover to cover, but it's contents remain unknowable to your waking mind. It's only lasting impression is a small bundle of items. Have books always done this?
Here's what you have:
A weird tree nut. It tastes strange.
Strange glyphs. You apply them to your skin with warm water. The air around you feels quieter.
A weird beet. Something's wrong with this beet. It's like a normal beet but with most of the beet sucked out of it. 
A small pile of flat dirt. From flat earth?
A strange candle. It smells like that day years ago.
Interdimensional beach sand. You try to pour it out. It resists, and then bends to your will.
Interdimensional beach sand scoop. Perfect for scooping interdimensional beach sand.
A false idol's likeness. You look at the date below the image. That can't be right. You learned in school that nothing existed before 30,000.
Rare leaves and branches. You've never seen one up close before.
A small bag. What's inside? You've never seen them before and don't know what they are.
A ball of fluff. Was this the end? Or the beginning? You've learned about this in school. Like all good citizens of your country, you already have a ball of fluff above each doorway.
Metal tooth. Looks sharp. sOMEONE'S missing a fang.
Coin. You try to flip it across your fingers, but it slips and clatters to the floor. You wonder if it has a chip reader.
Tiny planet. Like the kind you can get at those mall kiosks.
Analog clock, geopowered. It spins disorientingly.
The items pull the light from the room. You hold them close. You know you'll need them later. You pry up the tile in the corner of your room where you keep your other book, and hide your new, strange thing.
You go to your bed and sleep.
