Spirit Guide, Angel, Soulmate, Or Just My Dreams

I'm a female, 18 year old who has a very vivid imagination. Ever since I was young I would see images in my mind, see images in my head before bed, and see flashes of nature and random objects in my mind for no reason. When I was in middle school, I saw a blonde teenage boy in a black hoodie standing over my bed staring at me. The eyes were black and skin pale. I felt familiarity, but nothing bad. I blinked two times and it vanished in the wind. That was the first occurrence. A few days later I saw a old oval shaped frame with a blonde boy smiling. The age about 13. Years later onto my last year of middle school, my firmed who claims to be psychic too me she keeps having dreams of me and this blonde boy. They are reoccurring dreams that never seemed to end until she told me. Ever since she told me, to this day I see a image of a blonde boy smiling at me behind some sunlight. The image is bright. My friend told me his name was Anthony. A longing mystery, I have no idea who he is. And I never met him in my life. I would really appreciate if you could shed some light on what I might be dating with. Another thing that might help with you understanding the situation is that my ex in high school believed in reincarnation. He believed he was the lone boy I was talking about and that the blonde boys story and how I met him was when we fell in love around world war 1. He died in the war and I was his wife. The thing that really makes me not believe him is that my ex was obsessive so I think he was just saying that to make me feel a certain way about him. Now in present time I have a boyfriend who really is a good person and when we first met, he gave me such a familiar vibe to him. I felt like I've known him all my life and I can trust him with anything. Its stance to talk about because I've never really felt that way with anyone before. A side note is that I sometimes see a white string connecting him to me when we are hugging or really close to each other. Any thoughts?
