You pound on the door some more, slamming your body against it and sliding to the ground, wailing to get out. Nothing happens, except the wailing makes your throat hurt more.
You try the door to the bathroom, it's the same as the other door.
You look out the window. It looks like a normal sunny morning. You try to open it, but there's nothing to grab on to, same as the doorknobs.
"It's all just a dream. It's gotta be a dream." You say out loud. You climb back in bed. "So, I just go back to sleep, right?" You sit in bed for a few minutes, wide awake. You remember that if it's a lucid dream, you should be able to do whatever you want. You try to push your hand through the wall behind you. Nothing happens. Since it's gotta be a dream, you try to levitate off the bed. That doesn't work either, you just bounce on the bed a few times.
Just as you completely run out of ideas, the wall in front of you ripples again. It fades to show what looks like a stereotypical gray alien looking into your room, sitting in front of some kind of control panel. The owl thing is sitting on a platform or stool next to it. It looks like one of your snack bowls is on the alien's head. It smiles and waves at you.
