The Two To Never Be Seen Again

Hello there, this story is based off of a dream I had last night.
It wasn't really that scary to the point I'd wake up.
So, today, I'm gonna make a little story about what happened.
Hopefully you all enjoy.
Welp, I'm gonna give you a little (more like huge) description now.

This story is about two girls who wanted to have a sleep over with their three friends. So, they make a sleepover and their friends come over and stay the night.
One of the girls hear screaming. So, she decided to go and check it out, to make sure everything was okay. First she wakes the rest up.
When they got there, their other two friends look like they have seen something.
One of the girls ask if everything is okay, and what happened.
One of the other friends say in a scared toned voice that they needed to go back inside and quick.
If they didn't, something was sure to happened badly to them.
They all go back inside and went to sleep after a while. The two that were out there, went out to the same place again, like something was making them go back.
The other friends just stood there in silent. They swear they've saw something behind a tree, not too far from where they were. They tried to run back to the house then something happens-
One of the girls inside wakes up and wakes the other two up. She says she heard more screaming. Once again, they go check what's going on.
They see a shadow from where their friends saw the shadow.
Then boom, they hear a voice telling them to "leave" "run" "get out of here quick"
The girls were hesitated to go and check it out, but decided to run back up to the house, they see one of their friends' jacket and the other ones necklace, that was crossed shaped.
Then back in the house, the girls try and go back to sleep. Hoping that they were dreaming.
They hear the same screams that sounded like their friends from the last time.
But then it stopped, the noise stopped.
Everything was just...silent.
They go to the porch again, and nothing was there.
