Down a Time Hole

When you step out of your bed, you don't have much time to wake up. The reason being that you step into a big orange swirly hole on the floor next to your bed and fall right down it. While you don't realize it yet, you've stepped into a time hole. It's sending you to the past...but you don't know which past...yet.

When the swirly orange lights stop, you find yourself in an era of the past.
