At 3AM you are sleeping on your bed...

suddenly you open your eyes and you saw a shadow...

It's your sleep paralysis demon's shadow...which means you are having sleep paralysis and your sleep paralysis demon is Scaramouche.

you try to scream and move but you can't

Scaramouche: steps closer to you and staring at you with his scary burning indigo eyes

(Note: he is secretly in love with you)
