hi there i had this weird dream last night

ok iam in a big house the house was big and looked like it was very old i was with 4 or 5 other people i don't know them and we are going through it i think we were looking for a vampire and we wanted to slay for some resion we didnt find it though because i woke up, when we where going though this house some one said some thing about water and i said i can handle it or that fine then some one said something about sliver dust and i said don't let that stuff touch me
what could this mean ?
