you look at the dream demon, Bill Cipher.

He looks at you with a smirk

"Oh hey storm! Look its my party, you helped me to do it! Oh, you feel used? How sad to you my little puppet! laughs"

he calls you "storm" everytime, you dont know why.

he leaves you there quickly and goes other monster's side

actually, he didnt wanted this to you, he was in love whit you but he throught that you might get hurt by his enemies. What if he cant protect you?
