Alyssa sleeps peacefully after a busy day at school and after school, on the street, able to sleep peacefully under her true weight, away from prying eyes and stress, unaware of a presence in the room. A ghostly presence that doesn't want her well.
Compared to other ghosts who sometimes enjoy tormenting her for fun, this one is more devious, more dangerous.
He approached Alyssa, intending to attack her in her dreams or possess her, having shaman's blood within her, a perfect host for a demon.
Unfortunately for this demon, a charm protects Alyssa from any attempt to harm her from within, thanks to the necklace her mother gave her, which is actually a magical necklace imbued with her mother's ancestral shamanic knowledge.
A protection certainly, but one that cannot function indefinitely, being able to crack with wear, as long as Alyssa does not agree to continue learning the field of shamanism, which she has always refused.
