A short explanation later...
"So you two understand why I'm so scared for you two? I thought something bad had already happened.
But it turned out both of you are asleep in the bed like a pig if it wasn't for me knocking on the door."
"Hey, you're the one who told us to sleep until tomorrow morning. Besides, your story sounds like you're dreaming," Mary argued.
"I wasn't dreaming——"
Just before Alex could finish, someone suddenly knocked on the door from the outside.
"Don't check it. Just stay in the bed with us." Alex whispered as he pulled Sophia's arm back.
After waiting for a minute, the knocking sound reappeared again and again, sounding more urgent every time.
Yet the person outside doesn't talk at all, seemingly only knocking on the door on repeat.
"I told you I wasn't tripping," Alex whispered as Mary hid herself underneath the blanket out of fear.
