Is she into me or what is up?

When I am out with my friends i sometimes run into this girl from back in the day. We never had anything but we connected really well. We’re both 21 now.

Now she always tends to hug to say hello, but lately things have changed i guess.
One night she hugged me like 20 times and just last week she kept holding on when hugging me and it lasted about a minute. She doesn’t do this with other people

So now I wonder what the deal is? We aren’t really speaking outside of drunk conversations and back in the day we were kind of friends but at the same time had been into each other more than once.
As I said we don’t really speak much but I feel like the vibe is kind of different , especially in person.

Anyone care to provide me with their take?
