Am I subconsciously manifesting love into my life without knowing?

I don't know exactly what it is. But people just come up to me and just start conversations with me. I lost my grandpa these past years and that took a toll on my mental health . And ever since I've gotten out of my isolated shell 3 years ago I've been trying to find people to fill that hole in my heart that he had left.and I'm assuming since I've been looking for people and wanting love subconsciously for so long that random people who I thought wouldn't EVER bat an eye to me are speaking ,talking to and loving me out of nowhere.

Now is this necessary an increased vibration thing? Or something else entirely? I would love to hear your thoughts
