If I learned anything from my years of video games, it's that ghosts can't approach you if you're facing them. Thus, you should always go to sleep facing the door.
It's 2:00 AM in the morning. You suddenly hear a bit of a cracking noise and wake up because of it. Your state of mind is fuzzy, because you're trying to get back to sleep. Your eyes are half open and while squinting you notice your door is open and see your dark hallway. It's a bit too dark to see. You're very sleepy, so you don't think much about why your door is wide open as you normally close it or leave it slightly open.
You fall back asleep.
Some moments later, another cracking noise wakes you up again. You can't remember how much time has passed since the last time you woke up. You take a quick look at your clock and notice it's 2:03 AM. It takes you some time to process that in your sleepy state. "Ah, I just woke up a few minutes ago as well." You notice your door is still open and the hallway is still pitch dark. You stare at the hallway while trying to fall asleep. Your eyes won't close, it doesn't seem like you're getting any sleepier, even though you feel sleepy. Suddenly you notice it's not actually pitch black, but a shimmer of a shadow is there. While you stare longer at it, you notice it's a figure. Then you noticed the eyes. Someone is looking at you, staring at you in your eyes.
"I must be in some weird dream state", you think and you try to wake up a bit more to understand reality. But the shadow of a figure doesn't go away. In fact, while trying to clear your mind, the figure became more pronounced. Someone is there. This figure never moved an inch.
You feel a bit confused and try to rationalize it as a dream. You close your eyes for a few seconds and open them again. The figure, got closer. It's like it moved a foot more into your room. But it's still as dark as it was before and no more details can be seen from the figure. You stare at it once again, but no more details are showing up. It still a vague looking dark figure.
You remember that a ghost can't move if you look at it. Could this be perhaps a ghost? "There's no way", you think. You look at the clock again: it's still 2:03 AM. You turn back to the door and the dark figure has approached you even more. This time it went in much further than the last time you closed your eyes. You start to get a little bit frightened, but still thinking it's a dream. "This can't be real", you think.
You keep staring at this figure. It feels like several minutes have passed. Since your eyes are half open, you don't really blink much. But your eyes are getting a bit teary from never shutting them, so you take a few good blinks. But you notice the figure gets an inch closer with every blink. That shocked you and you suddenly open your eyes wide open. It's still as dark as ever. The figure is still as shimmery as ever. But the eyes of the figure are clear. It's staring at you.
The remaining night you keep staring at it. There's no sound, no movement. Just a figure. You just hope the night is going to be over soon.
Many hours have passed, you feel daylight should come soon. The figure hasn't moved since, since you never stopped staring. "Daylight, daylight" is your on your mind. Just a little bit more, as every minute passes by. It's soon over. You decide to take a quick glimpse at your clock.
2:03 AM
"No!" you screamed! You take a quick look at the door and notice the figure is gone. Nothing. You feel scared, but relieved, but also confused. "What was that!?" you said in a slightly shocked voice. You take a look at the clock again. You can't see it. Something is blocking your view. You look at a bit up and then notice it. This shadow is standing next your bed, staring you down.
You scream out loud, throw the blanket, try to punch, shake your head! But you suddenly feel nothing. You don't feel your bed. You don't see anything, everything is pitch black. It feels like you're floating in space while being completely numb. You don't hear anything. You can't even hear your own voice anymore.
Then you suddenly hear in your own voice, as if someone is playing a video recording of yourself say:
"Thanks for the invitation."

Yep, keep staring that ghost.
