I'm trying really hard to remember some of it...
I think I was on a spaceship, getting ready to go on an adventure. I accidentally pushed a button, which dramatically opened a secret purple stone passageway lit by torches. I was able to slide down the passageway and into a brightly-lit room filled with hundreds of random things, from plastic dinosaurs to maps and compasses. They were things that I was probably going to need on my journey, so I began to grab as many things as I could. Each time I picked something up, it vanished from my hands in three seconds and into a storage place where I could get them later.
I then later learned that the spaceship was actually in the depths of my bedroom. I was attempting to clean it, when a small opossum scurried out from under my bed. I scooped him up in my arms, not really concerned about what diseases he could be carrying. He was soft and warm, and I could feel his warm, pink tongue on my arm when he licked me.
"You know, you're going to have to let him outside," my mom sighed.
"I know." I opened up my bedroom window and put him outside. He turned and gave me a look before hurrying off to take shelter in a nearby well. (Yes, a well.)
