Amelia was sitting in bed with the lights off, watching a movie on her laptop. It was a romantic comedy about a girl trying to track down an old lover - exactly her kind of movie. Midway through the search, Amelia got distracted. The darkness behind her screen had disintegrated into a yellow glow. The light was back. This time she knew it wasn't a dream. The movie still running, Amelia stared at the door and reached for her phone. 12:07 AM. Jocelyn would be asleep. She called her anyway.

"Amelia?" A groggy voice picked up, "what happened?"
"It's back," Amelia said, "I was watching a movie and then all of a sudden yellow light started coming in through the door."
"Oh my God," replied Jocelyn, now fully awake. "Do you think someone is in your house?"
"No. There's no sound and the light isn't moving," Amelia said, knowing that the light would disappear as soon as she opened the door.

But at the moment, she couldn't think of anything else to do than to get rid of it. So she got up to close it. However, she had forgotten about the sounds and when she touched the door knob, she could hear them again.

Amelia realized that Jocelyn was still talking to her.
"Amelia? Hello? Can you hear me?"
"Yes. Joce can you come here? Let yourself in with your key"

After assuring that Amelia was alright, Jocelyn got out of bed, grabbed Amelia's key and headed out the door. What was going on?
