Needing advice spiritual
So context here, I live in an army base. I grew up on this base and have experienced things my whole life. I became friends with my neighbors and one of their friends I met, I'll call him c for now, c is a practicing norse and has Norse beliefs. I am pagan. He came to hangout after doing a cleansing for someone because supposedly the ex-girlfriend had done some things and left something behind. I had just felt off about his whole Energy when he was hanging out. I came home when something felt off. I felt like something was watching me and felt eyes. When I was locking the door I had heard 3 loud knocks from the outside. I have had things happen but never the knocks and the feeling of eyes. I am hoping maybe to get some advice on why this might happen thank you
