Why did my crush block me on snapchat after I tried to manifest him to like me?

My crush is a year older than me. We've never talked and he hasn't even noticed me at school but we live in a very small town so he probably knows who I am. I saw a tiktok about this 777 manifestation method yesterday and decided to try it to make him like me back. (i know this sounds crazy and I'm probably insane) But then in the same night he just blocked me without a reason. I don't really understand why he did it. We just used to snap but we didn't even talk. Today at school he noticed me first time. He looked me straight in the eyes. That doesn't sit right with the fact that he blocked me last night. Has he been thinking about me? Should I keep manifesting? I really need help!! And the most important, WHY DID HE BLOCK ME?
