I saw 555 and 369 right after

So I went outside today I walked around this busy area near my house there was a lot off ppl since it was Valentine’s Day. As I was walking I wasn’t feeling so confident since I have social anxiety and what not , I’ve been feeling anger I noticed along with sadness and loneliness. As I got away from the busy street I went to quieter street not so far away i sat down reflecting my thoughts and looking into the sky. 3 mins later a car comes by and parks as he parks the lights from the car made me notice the number 555 and to the next car infront of him . I then approach the car to make sure it’s the number 555 as I’m looking for signs since I’m not doing so well mentally. I then look back at the car that just parked thinking it had 369 on the license plate but it didn’t . Then literally like 5 seconds later on another car there was 369 on a license plate. What does this mean I feel like I’m going crazy
